Laptop randomly shuts down, possibly virus, power supply and more...

Question: Laptop randomly shuts down, possibly virus, power supply and more...

Thanks for your interest.

Ok, firstly,

..from that picture, it might have resulted from me have going on naughty naughty sites , ignoring McAfee site advisor, or me accidently clicking on an app in an un-legit version of Counter Strike Source, called 'Bot中英文語音轉換器'. I don't understand the Chinese. Came up with 'In English speech converter' in Google Translator. When I clicked on it, command prompt appeared and I think it automatically did something. The word 'Bot' seems suss. Can a virus be activate via the command prompt?
From that, could it lead to the hardware? I've been experiencing random shutdowns. Also this happened in the past days.
Before these bluescreens appeared, McAfee Internet Security Suite was alerting that my computer is a risk. But now, for the past few days, multiple scans and they're all clean.

Regarding power supply, could there been NOT enough power supply with my laptop's hardware? Which might possibly be one of the causes to my BSoD?;

BSoD when using Traktor DJ software when an external Traktor soundcard is plugged in

My laptop (Acer Aspire V3-571G running Intel Core i5-2450M ~3.1GHz, 8GB ram, 2GB nVidia GT640M graphics, Windows OS, 64-bit OS) is just a few weeks, old, with 1 year warranty. Bringing it to the store which I bought it from for some testing.

Also have been getting these kinda screens a few times:

Would restoring the OS help at all?

I have been researching about the computer shutting down problem, such as this:

Any help would be appreciated.

Preferred Solution: Laptop randomly shuts down, possibly virus, power supply and more...

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

i clicked "run" on a pop up without checking it out first, because, yes, i'm retarded. but i did, and about 3 seconds later the computer completely shut off and powered down. when i turned it on again, 1 or 2 minutes after booting up, it shut off again. this happened several times. now it won't even turn on at all. i've tried unplugging everything and waiting a while, but it still won't turn on. would a virus make this happen? or do i need a new power supply, or what?

I started having this problem about 4 days ago. I run my laptop with its power cord in all the time...wasn't doing anything and it had some stuff like AIM and word running and then just shut off.

I'd HAD problems with the AC power jack coming off of the motherboard before so I assumed it was a battery thing, but I hadn't gotten a battery warning. Wouldn't turn on...acted like it wasn't getting power even though the power CORD was lit up.

Took it in...of course, powered up for them and they found nothing wrong.

Has happened a few more times since then. Will just randomly shut off and then not turn back on. Sometimes for a few minutes, sometimes hours.

Can I rule out viruses and anything software related since it acts like it isn't getting any power when it is off and plugged in? (light should be blinking) Any ideas of what the problem could be? Hard to diagnose when the thing acts just fine at the repair place!

Answer:Laptop randomly shuts down, won't power up

I've been having the same problem with my laptop too. I have an IBM Thinkpad T23 and I've been running Speedfan recently and I've noticed that my CPU temp usually hovers around 154 deg. F or about 68 deg. C. I'm thinking that maybe it's the CPU overheating for the both of us. I've noticed that I can have it just sit there for over 3 days straight, but when I go to use it to write an essay or whatever, it'll shut off on me (The Prof. loves that one ). That's my reasoning on it.. and maybe that's why it didn't do that for the repair guys.

I have had this problem for the last maybe 10 days, and I have even talked to customer service about it. On occasion, the laptop power cuts off at random.  The screen goes blank for about 15 seconds, then the system shuts down.  I can turn it back on, but I must verify my identity in Windows before I can proceed.  (That's why I mentioned the OS in the subject line). I chatted with customer service, which gave me a set of instructions to restart the battery.  However, I did not write those instructions down, so my attempt to reset failed.  The power cuts continue. I would like to see the instructions re-posted so I can make a note of them and try again. Thank you.

Dear readers,

as the title states, my laptop randomly shut down twice so far when the battery was inside, but the AC power cable was in the computer. The battery icon bottom left indicated that it was 100% charged, running on AC power on High Performance and when I was in a game it randomly went off. Rebooted quicker than usual, skipping some of the startup processes it usually does when I manually turn it off.

The first time it did this the battery was very hot, even though it was running on AC. This time it is not, it is barely warm.

Another thing to mention is that both times, after being back in desktop, the battery would be "0% available (plugged in, charging)", but it would not charge, it stays at 0% until I remove it and put it back in.

I am having a problem while playing games as well, which we are discussing in another thread here:

And here is my original thread:

Hope someone has some insight on the matter.

Kindest regards,
Vadim Zinkovski

Answer:Laptop randomly shuts down when running on AC power (when battery is inside)

Some batteries can't take the electricity constantly flowing threw them i suggest you take the battery out when you plug it in the wall and put it in when your on the go. You battery does work still when you unplugg it from the wall right? And im guessing when your battery starts to fail it switches to "power saver" mode instead of "high performance" mode.
so take out the battery and plug it into the wall, store the battery until well until you need it. Hope this helps.
Also could be the result of a faulty battery..How long have you had your laptop?

So this time the problem started out as a simple issue. Whenever I bump the desk or move the keyboard out with too much force, the computer shuts off. Everybody told me that it could have been a loose connection so I checked it all and replugged everything back in. The computer starting working fine for about 5 hours then it just shut off randomly while I was playing a game. This time, though, it shut off without me bumping into anything. SO, is this a power supply issue? I'm using a 550-watt supply while running a 7800 GT. This is the right power amount so that's not my concern. And now the problem has gotten worse to the point where I turn on the computer and nothing shows up again. Windows doesn't load and the screen is on too. You here the fans and everything but nothing will load. All my parts from my old issue were replaced EXCEPT the power supply and CD-drive. I don't think it could be another loose connection b/c now nothing even shows up. Please help!!!

Answer:Power shuts off randomly, and any movement around computer shuts it off

Have you tried plugging into a different surge protector and different outlet?

Sounds like you need to swap the power supply to me.

Thanks, in advance, for your help. I'm not too savvy with computers, but know enough to know that something's not right...

This is a brand new computer-about 2 weeks old...just past the Staples return period. So I either fix it myself, or have to call for help. In the past few days it has crashed twice - we're not around when it happens, but when we have to turn it back on it says that it's recovering - then tells us that it was BlueScreen error [Locale ID 1033]. There are two MiniDump files from 5/30 and 6/2 when this happened.

The only new drivers I believe I installed was for a D-Link Wireless USB Adapter.

What worries me, though, is that 2 days after setting up the system, the computer was in Hibernate mode [I thought]-when I returned to computer, I could hear a fan running loudly but there was no response from system. I tried a hard shut down which it responded to. Turned it back on, communication w/ screen, no lights except the power button, and fan running pretty loudly. I tried unplugging it, etc. to no avail. Finally I plugged it directly into the wall (not the power strip), and it worked.. I figured my strip was bad or something. Now I'm reading that BSOD's can be due to power supply failures...

Anyway, any help you can provide would be great. Files attached. Thanks!

i tried turning on my pc today and none of the devices powered on and then i remember i recently installed a 2nd hdd to my pc and unplugged the power cable. And what do you know, my pc boots up, until about 5-10 minutes after a full boot up it shuts down. Is this a possible probleming occuring with the power supply? I dont know much about them so i can really tell you guys much, i only know its 630W. if you need anymore info ill be glad to reply.


Answer:possibly a power supply problem?

what specs are you running? and what brand of PSU have you got?

it sound like you might not have enough amps to power all of your devices... and so it fails when your CPU and GPU start going... we'll need some more info to help you out more

About a week or two ago my mouse would randomly not be detected upon bootup, it's a wireless mouse and pressing the connect button seemed to show it wasn't getting any power. It's a usb mouse but it's connected through a PS/2 adapter, which has not been a problem for 2 years or more now. Turning the computer off, removing the usb from the adapter and reinserting would return power to the mouse and then gets detected properly on boot up (mostly, on one or two occassions there was power but still not detected). Could the PS/2 port be crapping out? I'll be switching it to USB but it's not the main problem...

Once booted right up everything runs just fine and normal, no sluggish performance, crashes, or anything of the sort. However, in the past 4 or 5 days, after turning it off like I always do, it doesn't want to turn back on... at least until I go and switch the power supply off and back on. It does complete the shut down process normally as well, except for the keyboard. Once off it leaves the keyboard lights different than it used to. My mind is kind of failing but I do recall it would leave one of the four lights on (and this is a Logitech Elite keyboard), but now it leaves all four at a faint glow. The effect is also immediate, it doesn't matter if I try turning it back on a few days later or 5 minutes after turning it off.

I'm leaning towards pointing fingers at the power supply but before buying a new one I was looking to ge... Read more

Answer:Possibly unruly power supply?

Do you have the latest drivers from Logitech for mouse and keyboard before checking the psu.You should not have to turn off a psu using the switch on the back,not good for the rest of the computer parts.Your o/s should shut the computer down.

Hi, I'm fairly new here, but I am in need of some assistance. So I just installed my new parts for my computer. (A ATI Radeon HD 4890 and a 750 watt psu)It worked fined for about a day, then i went on for a few minutes, then my computer shut down. I tried turning it on again, but i didn't respond. I felt some heat, but very little coming from inside the case. I think my PSU may have over heated, but I'm not too sure.I am running Windows Vista x64, and I have a HP m9402f with the added parts above. Please help me! Thanks a ton. And merry christmas / happy holidays.

Answer:Power Supply issue. Possibly.

I  don't think it is the PSU. But maybe the new video card.Do this.Remove power cord.Remove, carefully, the new ATI card you put into the HP desktop.Put it back to the original configuration, the the video it came with. Plug power cord back it and try again.What happens if you do that?

I am having a very strange problem with my Toshiba laptop right now.
When the laptop is turned off and the power supply plugged in, the
battery receives a charge and will charge up to full. When i turn my
laptop on, for the first 3-4 minutes it will run on AC power then just
automatically switch to batteries and ignore that the laptop is still
plugged in. The adapter works just fine with my other laptop so I
cannot figure out what is causing this and hoping there is some
incorrect setting somewhere that is telling the laptop to switch to
batteries after a few minutes or something.

If i take the battery right out of the laptop, the front plug led green light comes
on when plugged in, and will power on and boot into the BIOS with no problems. The
laptop will stay on for as long as I let it sit at the BIOS without shutting off.
After I exit the BIOS to resume booting into windows, the laptop will shutoff just
after it begins to iniate loading windows. So, if i put the battery back in, it
will boot up normally into windows then run at full power (on AC) for only a couple
minutes then just switch back to batteries...even though the plug led is still lit
up, indicating that the laptop itself is plugged in. The laptop I am experiencing
the problem with is a Toshiba A70.

Any help is greatly appreciated.

Answer:strange power supply problem with win xp possibly

Which A70 is it? There should be a model number on the bottom.

While you look for that you can check out the Toshiba website and check out the FAQ's, and downloads they offer. It might be a common problem.

Earlier today, when I was in an adjacent room, my PC (which had been on all day) restarted itself without my assistance. I noticed this when I was watching TV and out of nowhere I heard the little jingle that plays everytime I log onto Windows. I'm not sure if it's related but I have my PC plugged into a UPS Power supply. I didn't have a power failure because none of my other electronics when off and back on like the PC did.

Is there something I can do (i.e. change the Power settings) to make sure that this doesn't happen again.


Answer:Why did my PC reboot itself? (Power supply possibly related)

It's most likely heat or failing power supply issue. I would check to see if all the fans are running and blow out the dust. I've seen cpu heatsinks that are totally plugged up with dust and lint. There are programs you can download to monitor temps. I think speedfan is one of them.

If the temps are ok, I would keep an eye on it. If it does it again, I would suspect the power supply...

When the computer is off and I push the power button the lights on the tower come on for a few seconds and you can hear the fan, etc. running and then it shuts off. After 3 or 4 tries it comes on and runs fine.

Tonight after coming home from eating out the computer was off but no one had turned it off so apparently it shut itself off. This was the first time it had done that.

I checked the power cord (seemed okay). I tried another plug (didn't help).

It has a warranty until December 2008. I don't want to deal with horrible customer service if it's something minor but don't want to void the warranty in case there are any future major problems.

If it?s just the power supply or the button, if me or my husband changed the power supply (we?d also dust it out) would that void the warranty?

Any advice would be appreciated.

Answer:Warranty and Possibly Power Supply or Button Issue

I think anything you do will give them reason to void the warranty, i would call or email whoever it may be and get advise to what you should do. ed

This is my computer: CyberpowerPC Stealth Raider 250 Desktop PC Intel Core i7 4790 (3.6GHz) 16GB DDR3 2TB HDD Windows 7 Home Premium 64-Bit -

I got this computer in November. I didn't used to have issues, but in the past two days my computer has been dying while gaming. It doesn't blue screen, it goes straight to a black screen and I have to hold down the power button to power it off and restart. Sometimes, when I restart the computer, there will be a BSOD notification (as in, the little window popping up just to let me know something happened), but not always. This culminated today in something like 3 crashes in a row within minutes of each other, and then I was unable to even see my screen as in when I turned it back on the computer's lights came on and its fans were running but there was no output to my monitor. I opened it up and tightened any connections (nothing was really loose) and tried again and this time it powered up, hence me being able to post this. My power supply is 450W and I'm thinking maybe that it just can't handle my gaming and I should replace it with a 600W supply, but obviously don't want to do that without being sure that's the problem.
I looked at the dump files and I saw they mentioned my graphics driver but I have kept it up to date.

It's within the one year warranty so perhaps I should just send it back.

Thanks for all your help.

Answer:Repeated crashing, possibly faulty power supply?


well according to the graphic card spesifications should be using a 500 watt power supply but i personaly would want something in the 600 watt range and with a good make like seasonic or XFX power supply. but wait for a BSOD expert to comment on your thread.

As the title says my computer shuts itselfs off, it started yesterday when I was playing a game, I don't think it has something to do with that though. Nothing special has been changed that would make it become this way.

First I thought some cable was loose but it turns off even if I'm not even near the computer. I've tried unplugging the HDDs and the DVD and looked if something could be disconnecting in some way but i can't find anything.
I have also looked in the BIOS if it was something like the BIOS settings turning the computer off if the processor was overheated, but it is not that, the computer is cool as it always is.

What happens when it crashes:
It suddenly crashes, doesn't matter what I'm doing at the time with the computer, it just happens. I try to start it up again and then it happens again, but this time much earlier, could be at the BIOS-boot-screen or the Windows-boot-screen, and again: it stops even earlier. If i let it be off for a while it works again a while, sometimes that also works after it has crashed.

I think it is the power supply unit, any other suggestions?

Answer:Having problems with upgrading Video Card and possibly power supply.

I take it the existing 6150SE is an integrated card (part of the motherboard rather than a card that can be removed)?

Even if not, to be perfectly honest you will need to upgrade the power supply as well. The majority if pre-built machines only have a PSU sufficient to power what it came with. A graphics upgrade will put significantly higher demand on the PSU.

How big is the case, you may find you are limited by the physical size available inside and may have to opt for a low profile card. If so, this in turn will limit what is available to you.

Personally speaking I find 4Gb RAM sufficient for my needs as a gamer, I don't however, play really modern high demanding games. I play more MMORPG game which are a little behind the drag curve as far as system requirements.

I read an article on how to get a switching power supply to turn on when it's not hooked up to a mother board. Now I just have to find out how to keep the power supply from shutting down when I plug something into it(car stereo, 12volt r/c battery charger, etc.). If I plug the stuff in, then turn on the power supply on it works fine. But if I turn off say, the car stereo then turn it on again the power supply shuts down. How can I get around this?

I'm trying to fix a friends computer she said it just shut off and would not turn back on.

What I have done so far

Used PSU tester on PSU, failed, replaced PSU. That got it to turn on for a few seconds then shut down.
Opened case, saw heat sink was dusty and clogged.
cleaned and reinstalled heat sink with Arctic Silver. Then it started running a little longer it would partially start up windows and crash when the pointer appeared.
Went into the BIOS to check the CPU temperature it seemed OK at 33-35 degrees Celsius, froze in the BIOS.
BIOS froze and shut down a few more times eventually that stopped.
Ran memtest86, passed.
Boot safe mode, worked.
Boot into an ubuntu live cd, worked.
Boot regular mode, worked once, now shuts down at pointer again.
Boot diagnostic mode, still shuts down at pointer.
removed the video card, stayed on, but no way to tell if it actually booted all the way.

I'm stumped. I'm not sure if it is hardware or software, because it was freezing and shutting down in the BIOS screen, but the RAM passed, the CPU heat sink isn't real hot, the hard drives sound OK. I also tried shorting the motherboard power switch pins instead of using the case switch, but that didn't seem to matter. I'm waiting for another friend of mine to get home so I can borrow his AGP video card and test that. Any other suggestions, bad motherboard maybe?

Answer:Computer shuts off had bad power supply

# Boot safe mode, worked.
# Boot into an ubuntu live cd, worked.Click to expand...

This tells you it is a driver; one that isn't loading in safe mode nor with a live linux distro.
If it were hardware, I suspect, you would have the same symptoms in windows safe mode and normal mode and a linux distro.

I just completed a new build. It powered on fine and I managed to configure BIOS but when it tried to restart the power supply immediately just clicked off. There was a small pause and the system tried to power on and shut off again. It kept cycling like that until I switched the power supply off.

Here are my specs:

Motherboard: MSI K9N2 Diamond
PSU: Coolmax CUG-950W
CPU: AMD Phenom II X4 955
Graphics: Using Integrated
1 120mm Fan
2 80mm Fans

I'm not quite sure what's causing the problem as the system managed to power on and run fine at least twice and the 950W PSU should be enough to run the hardware I have and then some right?

Hi Tech forum,

So i have a pretty puzzling issue that's been skin-peelingly fustrating to fix. I have an Acer Aspire 5552g laptop with a newly installed motherboard and ram that works perfectly fine with the AC adapter. However, once i unplug the AC adapter, the laptop shuts off with 10-20 minutes of usage. And it's not a normal shut-down. It freezes for a good 2-3 seconds, the fan kicks in, and does a hard shut off. No warning or anything. I made sure the connections where correct when installing the new mobo, per manual instructions (and some visual help on youtube) and it definitely does not overheat. I check temps constantly for any anomalies.
But it still shuts off when it is not using direct power supply from the AC adapter.
I figured the original battery was defective, so i purchased a new battery from acer that came in a few days ago and it's still happening on this new battery.

I flashed the bios with a current version from acer support site. I tried taking the battery out and holding the power button for 20 seconds to discharge whatever any currents that may be stuck i guess (read it somewhere on a forum). BTW the OS is windows 8 pro (clean install and updated drivers). I also have windows 7 home premium installed (dual boot/ with updated drivers as well) to see if the problem persists there as well, and it does. I figured maybe these windows OS's have problems so i tried booting a disk image of Ubuntu and it also does the same problem here too.

Hi all

This isnt an ongoing problem but since ive bought my computer at launch, every month or so, it will randomly switch off, and wont switch back on until ive unplugged the power supply for a couple of minutes then plugged it back in, then it will switch back on and work fine.

Is my power supply failing me? or is it being overloaded or is it another problem

Answer:Computer Sometimes Switches Off Randomly, Power Supply?

Chances are it is your power supply if it is turning itself off like that, try using a different kettle lead. If that doesn't work, I would replace the power supply unit, it shouldn't be that expensive. Are you getting any error codes before or after the system failure?

EDIT: Saying that, I have seen problems like this before simply from to much dust build up inside the system, causing it to overheat and shut itself down.

Recently I have been getting this issue more and more and its basically my pc shutting down not like when you shut it down normally or a crash or blue screen but just going down like you pulled the plug from the pc. I checked overheating in the processor and graphics card but that doesn't seem to be the case. It also only happens when playing certain games. My guess is that the power supply has gone bad and I need a new one but I'm not certain. Anybody got any idea?

Answer:Pc randomly shuts down like the the power shutdown

For PSU testing, I'd post over in the Internal Hardware forums for more expert advice.
As for determining the shutdowns' cause, let's try looking at these reports:
1)  Please provide this information (even though you may not be reporting BSOD's) so we can provide a complete analysis (from the Pinned Topic at the top of the forum):
2)  Please do the following:
- open Event Viewer (run eventvwr.msc from the "Run" dialog)
- expand the Custom Views category (left click on the > next to the words "Custom Views")
- right click on Administrative Events
- select "Save all Events in Custom View as..."
- save the file as Admin.evtx
- zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
- upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).
FYI - If we're looking for Event ID 41 errors (unexplained shutdowns), there's more info on that here:

I put all the hardware into a new case in case it was shorting on the other one, or the case buttons were faulty...

It has a cheap powmax power supply, so Im wondering if thats the problem?

Could it be the PSU? Or is it something mobo related?

Most likely the power supply, you have no choice but to try another one.

It could also be overhetaing if the heatsink is not properly making contact, so check to be sure thats on tight and that the fan is clean and works..

Hello R7 Community, About a month and a half ago in mid-August, I became the proud owner of my very first R7. And it was great! I used it for everything: schoolwork, Internet browsing, et cetera. (I do want to note that I am, in fact, one of those users with WiFi connectivity problems. I don?t want this thread to become a WiFi thread ? if there are any questions or comments, please see However, a few weeks later (this is around late August), my R7 started shutting off by itself. No warning, no hibernation, just off...completely. Processor, hard drive, display...everything. I thought maybe it was a fault of mine (accidently tapping the power button, for instance), so I didn?t look too closely into the issue. But then a few days later I noticed a trend ? my R7 would shut off immediately when I moved it. It was the strangest thing. I close the screen and move it to show someone else a document ? it turns off. I pick the laptop straight up and barely tilt it in any direction ? it turns off. It even got to the point that I could tilt the screen to utilize the Ezel hinge capabilities, and it would turn off. In short, it basically doesn?t like vibration or movement of any kind. (But let?s be clear: I?m making very natural, everyday use movements; in other words, no vigorous shaking or throwing.) So, in complying with BestBuy?s 15-day return/exchange po... Read more

Answer:Acer Aspire R7 Randomly Shuts Itself Off - A Power...

I want to confirm that the R7 has a security feature that requires the pressure from the middle screws to be applied so that the battery will discharge properly. This is in place to prevent discharge when the unit is being disassembled. I'm including a picture of the R7 I have along with the screws that are involved in this process. They required a torx #8 to tighten. I would be interested to see if anyone who continues to have this problem can try this and tell us if it is resolving your issue.
If you can't tighten the screws, or if you have and you continue to experience issues, it is recommended that your local support team.

I recently bought a Lenova 510S Desktop PC and an Asus monitor and everything was working fine. It has windows 10 pre-installed. Having used it for a few months, the desktop tower randomly shuts off power to the monitor, keyboard, and mouse, but stays on. The Monitor does not turn blue (no HDMI signal) but remains black. Lights on the keyboard and mouse turn off but the tower remains powered.

This is odd and it has happened twice now, almost once fortnightly and I don't know what is causing it. I am new to WIndows 10 and am unable to look for clues or error dumps. There is no error message and I cannot do anything. Pressing the CD drive, the drive functions as it should so there is power there. Trying to switch the usb cables to the other USB ports were of no help as they did not power the hardware.

I end up pressing the power button and forcing a restart. Everything else runs fine.

It is a very compact tower with 64 bit OS, GT530 onboard graphics, and I think a 180W PSU (I think). It has never been opened up before.

Has anyone experienced this or can help pin point the exact cause?

Was wondering if anyone knew of a system voltage monitor program that will log voltages or show a minimum/maximum for the 5 volt? I know there are a bunch of programs that will show a realtime display of voltages, but I want to be able to catch the condition and then look at the log for voltages and see if there is a dip detected that is causing USB devices to disconnect.It started at first at the front ports of the computer and I figured well I will connect direct to the USB port at rear of the computer in case there is a current dip across the cable to front panel USB. I use a 64GB USB stick as a extended storage to my SSD, and have some symbolic linking to this 64GB USB stick. When the USB drops this stick it breaks stuff. I tried with a different USB stick thinking maybe the USB stick was the cause so I grabbed a 32GB stick and populated it with the data that is at the symbolic link targets.

Hi guys. Ive got some major issues and have been having them for some time with my main box.

Specs are listed in my signature.

Basically whats happening is at random intervals the pc will reboot itself. Generally if i just leave it to idle its ok, But multi-tasking absolutely kills it.

The original suspect was overheating, However i dont think that is the problem anymore.

When i check my CPU temperature it sits pretty at about 47-48 (i bought a wick cooling gigabyte heatsink + fan etc)

Ive also gone and done a memcheck on both sticks of ram with memtest ( so i'm pretty sure its not that either.

At the moment i have one exhaust fan but i leave the case off almost constantly so i dont think thats going to do much help.

I hear the Geforce6 series are absolute power suckers so it would be logical that a new power supply would be needed.

Also it should be noted that unplugging all unnecessary devices (Cd/dvd-rw's, adapter cards etc) makes no difference to the pcs performance. She still reboots randomly, That is the reason why i am sceptical. I wouldve thought that if there was a lack of power that unplugging other devices would've made a difference?

Hello everyone,

My one-year-old computer started acting up a few days ago and I'd just like to hear your opinion.

It all began three days ago, after some Windows 8.1 updates. I was using my Favourites folder when it suddenly no longer responded. Everything froze and you could hear something slowing down inside until only the CPU was making noise. No blue screen or anything, just nothing at all. Pressing the onn and off buttons didn't do anything for a while either until I unplugged and replugged my cable. Suddenly the BIOS showed up and I rebooted the system. It started a bit slower than usual, and funnily enough, the time and date were no longer correct from that moent on. If the crash happened at, say, 13:00, the time was still 13:00 even if I had rebooted the system at around 13:10. I also did two virus scans, no infections found. The computer also worked properly, didn't become hot or anything like that.

This happened again a few minutes later, without the BIOS showing up this time, and I googled around. Some website led me to the Event Viewer which told me that some Kernel Power error had occurred (not 41, numbers varied too) and contained 'Warning: Processor-Power' messages. Someone in a Facebook group told me my motherboard might not be getting enough power. I don't know how the motherboard works, but we have no electricity problems in the house and my battery is sitll working.

It randomly shuts off even with the battery charged. it usually does it when it gets hot, or when i try to install something from a cd/ portable hard drive. I took the entire laptop apart, No HDD, only RAM and CPU. I believe its either the RAM, CPU or the Motherboard. I strongly believe its most likely the cpu or the motherboard. Can i get a second, professional opinion on this, would be greatly appreciated. Thanks.

Answer:Laptop randomly shuts off

Overheating will cause a sudden shutdown to prevent damage to the vital components. it doesn't necessarily mean one of those components is faulty. It could simply be caused by blocked ventilation slots in the laptop casing, so check them for fluff build-up.

Also make sure all fans are actually working.

I had a laptop which would overheat & shut down if it was used on my lap for a time. My trousers were actually blocking the ventilation slots. Although they are called laptops, they really need to be sitting on a hard surface to maintain a ventilation gap underneath it. I guess that's why manufacturer's now refer to them as "notebooks" so as not to mislead us about how they should be used.

I have an hip laptop and it randomly shuts off. I want to try to trouble shoot before I call it a lost cause. Referred to some great threads on here before so thought I'd give this forum a try. Thanks ahead of time for any help. I have an HP Pavilion dv6500. It randomly would shut off a few months ago, got better but started up again. When it shuts off its sudden like someone pulled the cord on it. After it shuts off I cannot get it to start for quite awhile afterward (20 minutes to 3 hrs if not longer). I can push the power button and the computer will attempt to start but will do the cold shutdown in the middle of startup. Sometimes it can get as far as the windows log on and then shutoff. The shutdown happens at all times, no pattern in my activity.

The computer has some other issues, I can't run it without the power cord because the battery is dead (HP said its because I didn't take the battery out when I used the laptop plugged into the wall. Refuse to buy another battery if I can't get laptop to work). My 3 year old spilled milk on the keyboard and it was bad enough the milk came it the USB ports and battery slot on the bottom.

Wow, after spilling milk all the way through it I would consider myself fortunate that it still runs. To me it sounds like it is overheating.

I'll try some other anti virus softwares but I don't think that's the problem.system specs:Dell inspiron 1525OS: Vista home premium (in the beginning) / now Windows 7 (prof)Thanks in advanceJonas

Answer:Laptop shuts down by itself randomly

If her OS is 32-bit, I suggest downloading Core Temp and running it to monitor the temperatures of her processor.  I think eliminating high temps as a possible cause may be a worthwhile troubleshooting step.

I have a Lenovo Y710 Windows 7 32-bit
Intel(R) Core(TM)2 Duo CPU T5450 @ 1.66GHz, 1662 MHz 2.00GB RAM
and it randomly shuts down when using full CPU process at 100% (when using facebook and youtube and anything else gets to 100% process) I am pretty sure it is not a virus though because i already checked the computer for viruses o and also shuts down when i barely started up the laptop so how can the virus even load i already re installed windows 7 still shuts off and blowed the fan with can of compressed air even opened the laptop and cleaned the dirt off

Also i do not know but it maybe started since i tried over-clocking the computer but most likely i under-clocked to much with (NHC) program because now in cpu-z it says core speed at 997.2 MHz and in everest its says under the
Overclock > CPU Speed > CPU Clock "997.2 MHz (original: 1667 MHz)" so thats probably why its at 100% process with so little programs open so if some one can help me overclock it again thanks

Also in my motherboard name it says just "Lenovo Invalid" so i dont know what motherboard I have and I cant update the bios but its pheonix so i dont know where i can update it already tried the website but can not find where to update it

any help would be appreciated thanks

Also My core voltage is at 0.950V i dont know if this has something to do with the low performance but any help would be appreciated any time now thank you

I dont know what happens, is just shuts up, even if the battery is charged. It is a toshiba satellite, just 6 months old.
I dont know if i hit a key that shuts the system or a heating problem.

Answer:The laptop randomly shuts up

Get a can of compressed air and blow out all the fans. Then go to Control Panel/Power Options. It probably is set to sleep after 5 minutes of non-use without the power adapter attached to save battery power. You can readjust this if you like.

recently i have been having trouble with my laptop (toshiba satellite, running windows xp, about a year old). it seems to randomly shut off at times, often causing me to lose whatever i am working on. often it happens when i am in the middle of a game or in the loading of a game, but even happens when i load different applications or watch websites with flash/music playing. the fans usually get pretty loud, and then the laptop shuts off all together. the laptop is just about always plugged in, not running from battery. if anyone knows any way i can fix this without sending it into the manufacturer i would be most grateful.

Hello all, over the past year I could say I have been been getting a lot of random shutdowns with my Dell Studio 15. This can happen when I'm browsing the web, trying to play a game, or I leave my laptop on for a extended period of time (a day or more). I realize a year is along time to wait to solve a problem, but better now than never. My laptop is a Dell Studio 1555 running Windows 7 x64. Sometimes when I turn my laptop back on I can hear the fan running rapidly, yet when it shuts off I do not hear it. I believe these are due to heat and I just need to clean out my laptop. If and when I leave it on I come back to find it has restarted and most of the time there is a not a Blue Screen notice. Usually in this situation I just left my laptop on or I am streaming media. Sometimes it will Blue Screen but most recently, within the past few months it has not. Today it actually has produced one. Unfortunately I believe most logs are deleted due to my use of CCleaner and TuneUp Utilities, but I do have Critical events in my Error Logs which date back to 2 months ago.

I look forward to solving this problem. Please and thank you.

Hi guys,

So for the past 2 days my laptop will randomly shut down in the middle of working. I noticed that it shuts down when I seem to be pushing computer as in, if I'm playing a game that demands a lot of RAM or processing my data from work which again pushes the computer. But once the laptop turns off, if I immediately try and push the on button it will turn on and then immediately shut off, I have to wait about 15 minutes for it to turn on. Something to point out, right now, my battery is 100% charged but when I try to turn it on, the battery charge light lights up. Not entirely sure but some advice would be appreciated, thanks.

Some history with my computer...recently I tried to uninstall my AVG in order to register some network stuff at my university and I was getting errors with that. For the past year, my battery would not charge beyond 60% but in the past month it has been able to charge to 100%. Nothing was done to fix that. In addition, For about a month or so, when I start to push my computer and open up several programs, it makes this "whirring" noise which lasts for quite sometime and then randomly will stop. That didn't change anything in terms of productivity or function for the laptop. But now it just turns off.

This is a difficult question. I have an ASUS K72J series laptop that is over 4 years old.
My laptop shuts off randomly in high power demanding games (no warning/no lag). It is NOT hardware or heat. It is NOT the power supply. That really only leaves software but I am at a wits end trying to figure out what/why/how. I have updated all drivers and DriectX. The computer works fine - hours on end - but as soon as I try to play a 'heavy' game it lasts about 5-10 minutes and then shuts off. (These three games have triggered it - Borderlands 2, League of Legends and Farming Simulator 2).
This issue bagan about 1 month ago after I recieved my laptop back from a proffessional computer repairer, as I had my display cable replaced (this was a separate visit from the one where I had the thermal-paste re-done). I will stress that it had never happened prior to recieving my laptop back. However I don't know how that could be the cause - it was pointed out to me by a friend that It could have something to do with full-screen games and an issue with them that closes it, I haven't tested that yet by playing them in Windowed mode.
Here is some further explanation:
Power Supply: I have run Borderlands 2 on battery power only, AC power only and on AC + Battery power. Same shut down problem happened everytime.
Heat Issue: I know it is not heat as I had the heat-sinks and thermal-paste re-done. Also the computer place I took it too ran a stress test and had temps up around 90C (and i... Read more

Answer:Laptop shuts off Randomly

Hi Rinkashime,
So the computer place that seated and used the thermal paste, could be the issue.  Let me explain.
Asus computers in different models have this issue, and its usually after a repair.  More than likely the repair place removed the thermal pad, and replaced it with thermal paste.  Pads are the tops in GPU and Process heat transfer.  at 90C I would be a little worried but at 65C you should be OK.  Assuming that your device is OK with the connection of the Processor and the heat sink (meaning there are no air bubbles or gaps allowing it to surge, etc then I would look at your BIOS settings.
In most, not all BIOS settings, you can select and change the max and min shutdown temp for the machine.  Are these present?  If so are they sent about the temps that your device is throwing at you?  I would check.
Here is a overview of the Asus you have, including temps, how games handle and a given stress test they used.  Take a look at it and see if your getting the same numbers.  If you are not, then I would check the BIOS (make sure you keep it insides the guidlines for the processor you have, dont want to fry it).
I would then get the thermal paste or pad reseated and try it again. 
From there I would need a lot more info on what your computer has, etc.
good luck

Hi everyone,

I have a HP xf335 notebook, that about two weeks about began shutting down randomly for no reason. I and running windows xp home. I have contacted HP and have updated the bios, cleaned the fan vents, changed some of the recovery settings. Still nothing seems to fix this problem. I think that it might be over heating only because when I first turn it on it will run for about 20-30 minutes before shutting down. Once it shuts down, it doesn't stay on for more that 30 seconds if that. The bottom also seems pretty hot. But I can hear the fan running so I know that it is working okay. I then thought that maybe the battery was bad but it still happens with the a/c adaptor connect by itself. I even tried to discharge the notebook but it still happens.

Does anyone have any suggestions on what might be causing this problem.

Hey everyone,

I have two problems with my HP Pavilion zx5040us.

My first problem is that it randomly shuts off. I was thinking it was overheating so I took it to the shop where the guy put some silver paste in there to cool it and I even bought a laptop cooler.
As soon as I turned it on I used it for 10 minutes and it shut off again.

My second problem is that my laptop can only work with the AC Power cord. I thought my battery needed to be replaced so I ordered a new one. As soon as I put the new one in... it still didn't do anything.

I downloaded the latest BIOS update too. I better wrap this up before my laptop shuts off again. Any help is appreciated. Thanks.

Hi there,

I have a problem with my dell laptop. It shuts down at random, and then I have to go through Windows Error Recovery when trying to reboot.

I have contacted Dell on numerous occasions and last week sent it back to them. It was returned with a new hard disk drive and heatsink. The OS was reinstalled with Windows 7 HP 64 bit.

The laptop seems to shut down when I am actively typing, into a search engine, and clerical work in Microsoft Office.

I have been trying through trial and error to find out when it happens.
1. When I attempted to go on the internet, it lasted 10 minutes and then binged at me and shut down(it always comes up with '10' in the address bar).
2. I disconnected the internet (IE8), went into internet options to delete any cookies, temp files and browsing history but again it binged a me and shut down.
3. Connected back to the internet and tried to get mozilla firefox, but just shut down. Then had to go through the windows error recovery.
4. Took IE8 off and loaded Microsoft office. Went into Publisher and it shut down.
5. Opened Microsoft word 2010, began typing. It binged at me again, the find and replace box popped up, then the save you document box popped up and it then shut down.

Any ideas? Does it sound like Hardware or software fault? Its only six month old and I'm having trouble gettiing anywhere the Technical Help rom Dell.

I'm having an odd issue with my HP Pavilion dv2000 laptop. Sometimes it will spontaneously shut itself off. First, the screen will go out. Next, the computer itself will shut down. This always occurs when I am doing something that requires a lot of resources, such as playing a game or watching a video (but only when the video is streamed, it handles DVD and avi files just fine). In retrospect, it's 99% game related.

I think it may be heat related, as if I try to boot the laptop after it shuts itself down, it will shut itself down again before startup is complete. If I let it cool down for a while and then come back to it, the computer will boot properly. As well, these shutdowns are always accompanied by high temperatures on the left side.

Running SpeedFan right now, the hard drive is at 64 degrees C, Temp (ACPI) is 92C, the processor is at 82C and the video card is at 105C. It does not recognize a fan.

I hope that helps. This is not my area of expertise so I've exhausted my options.

The computer is 2-3 months old, and running Windows XP (Home, I believe).

The problem is that it shuts down randomly.  Sometimes it will go a few days and sometimes only 15 minutes before the thing shuts down. Although i wasn't really paying attention, it just happened in front of me.  The system seemed to go to sleep but when i went to wake the laptop, the system started up from a full shut down (i had to log in and all applications were closed.)  There are no special warnings indicating that the system had an unexpected shut down..  
I had hoped that i fixed a similar problem on this system a year ago when it was also over heating.  No more overheating but still shutting down.
The system in question is a Samsung NP-R580 running Windows 7 Home Premium 64-bit.  i3 2.4GHz; 4.00GB RAM.  We're running Norton 360 Premier for anti-virus and firewall.

I have a sony laptop that is doing something very strange. It is just randomly clicking and going completly off - and then automatically restarting.

This happens as I'm working on it and can be when I am doing anything. Typing, moving the mouse, there doesn't seem to be any one thing that makes it do it. But it does seem to be doing it more often.

I conect it with two different power cords - one at home and one at my office - yet it does it at both locations so I don't think it has anything to do with the power cord.

Hi, hopefully someone here can help me.

Recently while I was using my laptop it shut down mid-use and wouldn't restart.

It doesn't seem to be receiving charge from the mains adapter (no light on the charging indicator).

Eventually, after about half an hour or so it would allow me to turn it back on again with the power button, but after minimal use the same thing happened again.

This process has now happened several more times. After the shut down/crash I will not be able to turn it on again for an extended period of time (perhaps 30 minutes) and the laptop is completely unresponsive.

Once I do turn it back on however, almost any use will trigger the shut down. It will last for several minutes while I don't try to use it (I did manage to use control panel), but as soon as I even open a web browser the system crashes.

This may well be a hardware problem, so perhaps I posted it in the wrong section, but I didn't want to assume it was just a faulty PSU, as there seems there may be something trying it.

If anyone has any advice or ideas please let me know. I'm pretty competent on software, but not so great with hardware issues.

Hi,I have a Lenova 510S Desktop PC (few months old) and an Asus monitor and everything was working fine. It has windows 10 pre-installed. Over the past month, the desktop tower randomly shuts off power to the monitor, keyboard, and mouse, but stays on. The Monitor does not turn blue (no HDMI signal) but remains black and powered. Lights on the keyboard and mouse turn off but the tower remains powered.This is odd and it has happened twice now, almost once fortnightly and I don't know what is causing it. I am new to Windows 10 and do not know how to find out more about this. There is no error message and I cannot do anything. Pressing the CD drive, the drive functions as it should so there is power there. Trying to switch the usb cables around to the other USB ports were of no help as they did not power the hardware.I end up pressing the power button and forcing a restart. Everything else runs fine.It is a very compact tower with 64 bit OS, GT530 onboard graphics, and I think a 180W PSU (I think). It has never been opened up before and I cannot tell when it will happen again but this is not normal.Has anyone experienced this or can help pin point the exact cause?

My Equium A60-692 has stopped receiving any power from the AC adaptor (tho I've metered it and its giving out a good 19v). I've noticed the end of the adaptor (the end that goes into the laptop) is different to normal ones. Rather than having a hole at the center that a spike on the laptop fits into, its just got a flat piece of metal. Just wondered this was normal and the problem is inside the laptop or if the spike has somehow snapped off and is stuck into the adaptor. It looks like its supposed to be this way but it seems a bit weird...


Answer:Equium A60-692 Power supply - laptop doesn't receive any power

HI Rodders,

Bad news I'm afraid. The flat piece of metal that you describe is the back end of the central pin that has snapped off the inside of the power socket on your notebook. This is quite a common occurrence (check out some of the other posts on these forums).

Unfortunately the solution to this problem is for your nearest Authorised Service Partner to replace the mainboard (quite expensive!) unless you can find someone willing to solder in a new power socket.

Very sorry to be the bearer of such bad tidings.

Hey, I've got a  annoying problem with my laptop and was wondering if I could try to get some ideas on how to fix it.Lately, my HP pavilion has been suddunly shutting down(in like the way it does when it overheats) what seems to be prematurely, with maybe about fifty percent battery(but it isn't always at this point in time), when I don't plug it in.  There's no indication of when it will shut down, no warning, and the laptop always indicates that there's still at least some charge left when it does. I don't think the problem is overheating as this doesn't happen when the laptop is plugged in.It takes the laptop to be plugged in for the laptop to start up again.I would try to drain the battery but its premature shutdown keeps me from doing just that. Any suggestions?

Ok, so I am working on a laptop for my buddy's wife. It is a hp pavilion dv9700. Obviously enough the title explains it all. I have blown canned air through it and it seemed to run for about 3 hours in safe mode while I defraged it. Logged back on and tried to preform update to sp2 and crashed in the middle. Luckily it turned out just fine. I don't believe it's due to overheating because the bottom and the keyboard aren't hot, at least not compared to any other laptop. I have tried to replace the memory and it still happens. Anyone have any ideas? I'm so stumped. SystemInfoEdited.jpg picture by dragonpoet88 - PhotobucketHere is a link to her system Info. I had to edit it because she used her first and last name as the user. And also she actually has 4gb of ram installed, there is just 3 because I tired to replace it with my own as previously stated. Well, thanks for the help in advance.

I have read some stuff where its the thermal paste. How would I go about replacing that?? And is that a symptom of anything?

And when I say "shutting down", it shuts off. No log off screen, no BSOD (blue screen of death), just off.

And It's not when it's normally running when It's shutting off. It's shut off in safe mode and I have even seen it shut off on the screen where is says "press F2 to blah blah blah" when you first turn the laptop on.

Answer:laptop randomly shuts down not overheating

First we have to try and diagnose before trying to fix
I am starting with the assumption that it works ok in safe mode. If it does not we should look toward a hardware issue. I am focusing on software

If it works in safe mode try with a clean boot.
How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7
If it does not shut down, follow procedue. If it does shut down go to next step

Download and test for overheating (your touch the keyboard method is not a recognized overheating test) by using speedfan.
If it is overheating thats the cause if not follow next step

I guess this has to be done in safe mode, although no the best way. Download malwarebytes and run a full updated scan with that and your anti virus.
Negative go to next step

Go to event viewer and give me the codes and explanations of the various shutdowns.

I can hear something running and wondered if it could be the fan and it shuts down due to overheating. Could anyone please help as it has hardly been used. Thank you

Hi there! So my laptop has been shutting off randomly and repeatedly for a while now, I am NOT tech savvy so please speak simply and give detailed instructions! Thanks!!
Some details --
I'm pretty sure it's not a heat thing, looked at the temps with some app and they are normal.
I also performed a system refresh already and problem still persists in case that helps.
No blue screen of death - computer just shuts off as if the power is cut and I can start it up normally. Sometimes shuts off a few times in a row immediately after I power it back up, but usually just turns off randomly once every day or every other day.
I have an ACER Aspire S7, intel core i7, running windows 8, not really sure what other info is needed. Thanks SO MUCH for your help in advance!

Answer:Laptop randomly shuts down - NOT overheating

Oh another thing - sometimes my laptop shuts off while I'm using it, but sometimes it shuts down while it's sleeping. So I would close my laptop (which puts it in sleep mode) overnight, and when I open it in the morning, it's completely shut down. Thanks!

a friend gave me a laptop and i was cleaning it up when it started randomly shutting off. first i was doing a cleanup and it shut down during a malwarebytes scan. then i rebooted and it finished. then when installing avast right when it started coping files it would shut off. when it shuts off its like your pulling the power out so there's no errors in the log or minidumps.

i tested the hard drive and its good. i ran memtest86 and after about 6% tested it shut off. i tried each stick individually and in each slot and it shut off on every one of them. then i tested the ram in another laptop and they passed. i left the laptop on all night long and it was still on when i got up.

i'm stumped. all i can think of is blaming it on a bad memory controller, but i think thats just an excuse that sounds good.

Answer:Laptop randomly shuts off without errors

The laptop may be overheating. Are the CPU cooling vemts clean and free from dust? The laptop may have to be opened in order to clean the area well

When I close the lid to my laptop (HP Pavilion) it will sometimes shut off. Sometimes it does it and sometimes it doesn't do it. In the power options I have it set to "do nothing" for both plugged in and battery for when the lid is closed but still for some reason it'll sometimes shut down.

I'm not sure if this has been asked and answered before, but there are just too many threads to go through them all and a Google search didn't turn anything up for my specific problem.

Any help would be great!

So my computer keeps shutting down. I just bought a replacement battery for my computer so I don't think it's a battery issue. I read some previous posts abut Windows 7 not reading their battery status correctly and shutting off the computer with a 50% battery message. However, If my computer shuts off with the battery attached, I am still able to turn on the computer, run windows startup, and load programs. Similarly, my AC power adapter is still able to charge my computer.

I don't use up a lot of memory either. I ran my virus protection software and it said that my computer was clean. Additionally, my computer doesn't seem to be overheated and there's nothing blocking the fan.

Any suggestions for narrowing down the problem? It started a few days ago.

Answer:Laptop randomly shuts off with no warning. Please help!

Have you run a temperature program to make sure the laptop is not running to hot?

Such as this:

Speccy - Advanced System Information Tool

Please then upload a screenshot of it with something like the snipping tool.
Please follow the above tutorial, and if there is anything you do not understand-ASK

Do you hear any unusual noises?

Anything unusual at all when the issue occurs?

Hello, I'm new to the forum, but I have been following it for some time. I seriously hope someone will be able to help me.
Here is my problem: I bought a new ASUS laptop 3 months ago, and it was all okay until it started to shut down on its own ( about a month ago). I tried resetting Windows, updating etc then I replaced my hdd because a software diagnostics tool reported that there were bad sectors. I could also hear strange noises. I read that manhandling the laptop while it is running could damage the delicate workings of the hdd, and I had done that sometimes. Everything was fine for almost a week, then the computer started shutting down on its own again. It happened while I was working , keeping multiple programs open (twice, hours after turning it on) and while I was watching a video (10-15 min later). However, today was not the first time I watched a video, so the issue is new. It seems like it is gradually worsening. After it shut down, I tried to power it back on, but it wouldn't boot. The LEDs didn't even turn on, unless it was plugged in. When i unplugged the charger it shut down again immediately. After 3 minutes I removed the external power supply, and it kept running.

I have already updated the BIOS firmware to the last version, but it obviously didn't work.
ASUS PC Diagnostics tells me that the CMOS pattern test failed, I looked up possible solutions, but I wanted to ask before doing anything stupid.
I am pretty sure it isn't a heat ... Read more

I recently purchased this Acer Aspire V3-531 laptop to replace my Acer Aspire netbook which had provided faultless service for 3 years. The new laptop works well, however, I have an intermittent problem when the laptop will shutdown/restart mostly straight after waking from sleep mode and once while idle.

First post on here and my tech levels are basic/competent. Any assistance would be appreciated.
