Preferred Solution: cant turn computer off

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.)

Answer: cant turn computer off

hello ,

this is just for starters to help diagnose maybe even fix !!

now what i need to do is go to your (device manager)

now once there you will want to select from the toolbar of the window(veiw) then a drop down menu / from it you will select (show all hidden devices)

now if you see any (red or yellow) quotation marks , make a note of what they

now go to the (event veiwer) this is thru the (administrator tools) in the control panel
here you will find 3 to 4 subcatagories

you will want to check each of them for this is where windows keeps track of all errors
now you will want to make notes of the errors that have been recorded ( you do not have to make notes of double entries just of the dates of their happenings & how many there is)
you will get more information on the errors if you (right) click them / then select properties


do you have a Windows Xp cd, not the restore cd's that come with some systems, the cd will have the Windows logo & 3D hollowgram/image on it

if you do not maybe you can barrow one from a friend/family member/co-worker as long as it is the same version that is on your system

if you have (Windows XP Home Ed. sp2 ) then the cd will have to be that / if you have a cd with (Windows XP Home Ed. )you will have to slipstream (SP2 ) onto a disk that you create

this also applies to (Windows XP Professsional )

now if you do have the Windows XP cd with sp2 please follow these steps


performing a (sfc) system file checker

It is a scan that checks the core files & dlls of the (os) operating system and replaces them if they are corrupt or missing with the correct original version


#1 then select (run) , then press enter
a window will open
#2 type in ( cmd ) then press enter
another window will open
#3 type in ( sfc )then press enter
another window will open
#4 type in (sfc /purgecache) then enter / your pc will work like crazy / this helps in rebuiding the cache file (notice the space between (sfc & /)
#5 type in (sfc /scannow ) then press enter ( notice the space between the (sfc & / )

now a scan will start , have your (Windows XP software disk ready ) your pc may ask for this disc when it starts or during the scan( so you must sit with the pc while this scan functions ) , if it does then incert the cd into one of your cd/rom/player's , your pc will then reconnize it and continue , you will then have to minimize the splash screen for the cd to see the scan , when the scan is finished you will need to close the cd and all open windows , then remove the cd

you will then need to do a ( Disk Cleanup ) , then empty the caches & temp files thru the (Internet Options) , then do a defrag

restart your pc

then do a defrag again after the reboot

then get back to us

I have a bit of a strange issue with my computer. Forgive me if I'm a little too descriptive, but I'm not sure which details are relevant and which are not for such a problem. First, the specs:

Model: eMachines T2984
Operating System: Windows XP Service Pack 2
Processor: Intel Celeron D Processor 340, 2.93 GHZ, 256K L2 Cache, 533 MHZ FSB
Power Supply Unit: Bestec Model: ATX-250-12E REV: P7
Motherboard: I can't tell, but it appears to be an Intel motherboard by the number of Intel labels on it
RAM: 512 MB DDR SD originally, added 1 GB a couple of months ago
Let me know if you need anything else...

Yesterday, I got home from shopping around 1PM, and I tried to start the computer. I pushed the power button, and nothing happened. I checked all of the cords, and they were all plugged in. Not knowing what else to do, I opened up the case to see if there was something obviously wrong. The only thing that I noticed (other than a bunch of dust) was that the power supply unit was still hot. I shut the computer down about 5 hours earlier after about 20 minutes of use, so it seemed strange that the power supply was still hot. I unplugged the computer just in case there was some sort of fire hazard.

At this point, I called a friend who suggested that the problem might be with the motherboard or the power supply unit.

A few hours later, I plugged it back in to try to get it to work. As soon as I plugged it in, the entire unit suddenly started "running" by itsel... Read more

Answer:Computer Doesn't Turn on, Fans and Some Lights Turn on Automatically

I would suspect that the Power Supply Unit (PSU) is going south. If you have a spare one laying around, install it and see if the problem goes away.
You can buy a new,better PSU from Newegg for about $40.00. I have used a Thermaltake 430 watt in one of my machines for some time now and it works well.
You will have to check the size of your PSU to be sure a new one will fit into the eMachine.
Here's the page with that PSU on it. It's the last one on the list.

I just put together my first computer 6 months ago. It abruply shutdow in the middle of writing a paper for school. I couldn't turn it back on right away. after trying a few times, it turned on. All the fans are working even the fan on the power supply, the motherboards lights are on. My graphic card in on the motherboard. I think it might be my power supply because when I first put it together I didn't plug in the smaller power connection to the motherboard and the same thing is happening, black screen. It's like my computer isn't giving my monitor any feed. I will have more info when I get home. I can't get in to bios or safe mode.

after serching all night to find out why his computer is in limbo, i leave my brother's house without finding needed help. his computer won't turn off...the fan, a couple little lights until he unplugs it from the wall. first, the computer did a restart all by itself, he said, then it would not turn on, except the fan and little lights inside that won't turn off. he took out the hard drive and it functions in his other computer...he puts the hard drive back into the new computer and it will not turn on or completely turn off that fan. he tried the "hold the on/off button for at least five seconds" step and nothing changes. he has had the computer for a year and a half, so he really wants to figure this out. how can he even get it to turn on so he could do a safe start up? so far we cannot find a way to troubleshoot. he have checked the cords, perhaps there was a freeze up that began this loop and that's why the fan stays on? please say this is something you have heard of and there may be a solution. the advice we have found usually goes back to buying a new computer. thanks in advance, tea

I am using a client computer that is connected to a modem via a LAN cable which is in a neighboring house as far as about 50 meters. The host computer is there. The host computer is only using Internet Connection Sharing (without a router) to share its Internet connection with me. Within this network there are only two computers, the one I use (as client) in my house and the other one is the host computer as I mentioned earlier.

How do I know that the host computer is being turned on or off?

The purpose is to know so that I can use all the bandwidth from the modem when the host computer is not turn on. Because there are no restrictions on bandwidth from the host computer, and I just wanted to use all the available bandwidth only when the host computer is not turned on.

Both computers use Windows 7.

I use my laptop for school and, by keeping it on power saving mode, usually get through two school days without charging my laptop. Ever since I've downloaded Windows 10, (1) my computer doesn't shut off all the way when I close it, which drains the battery, and (2) every time I charge it, it turns off the power saving mode, which is really annoying. This is especially annoying when I don't notice it isn't on and my battery drains even faster. Is there any reason it won't turn off? Is there a setting I can use to keep the power saving mode on at all times?

Answer:Why won't my computer turn off all the way and why can't my computer stay on power saving mode?

Your system might have a virus, try to scan using Malwarebytes, Superspyware , Trojan-Killer. Restart your system then try to download Hitman Pro then Run it. Then optimize your system using Ccleaner. Hope this would help.

Hi TheRealDanny.

The crash dump (a Stop 0x3B one) is not saying anything in detail about the probable cause of the BSOD).

Test your RAM modules for possible errors. How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.
If it does not show any error, enable Driver Verifier to monitor the drivers. Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

i also recorded a video of how its sounds like:
so please help/B]

Answer:Solved: computer beeping sounds when i turn on computer

There are three possibilities here, all related to your memory.

1) You have forgotten to fit your memory back in.
2) Your memory isn't properly seated in its slot(s)
3) You have killed your memory because of not following antistatic procedures.

I'm suspecting it is either 2 or 3.

As the title said, my computer freezes during games. When it freezes the screen just stop at the last frame (so no black screen or anything like that) and I can hear the game for about a second before it turns to a low clicking sound. At which point I have to manually shut down the computer and restart it. Nothing else works. Then I get the usual question of how I want to start the computer, I always pick “start normally” and it’s like it never happened.

I think it’s because the GPU is overheating, because that’s the only component that’s really hot. When I check the temp while playing it’s usually building up to about 60C (24-30C on idle) and stays around that number. And it fells really hot when I touch it after it’s happened. The only problem with that theory is that I can play every game out there usually on the best setting (haven’t tried every powerful game out there) and not a single problem with lag or such. Then again, I’ve never had that problem with MW3, and the temp stays around 50C on that. Not to say that the GPU is really that great. It’s average at best, but I’m not a hardcore gamer or anything so figured I didn’t need the best.
I built the computer myself in June 2011. And it went fine without any problems until maybe 6 months ago, not really sure when it happened.

Here’s what I’ve done so far

First of, my monitor exhibited signs of flickering during start-up, but only minor ones and would just stop at the 'Welcome' screen of windows so I didn't give it much thought. Iv'e been using it with the cpu the same time I bought the monitor.

But after some time, the flickering got worse. It went from 1-2 second interval flickers to a whole 10 seconds of blackness before it showed anything.

Now,Iv'e got a new cpu but still using the old monitor. After a day or so, the monitor exhibited the first symptoms of my first cpu, so I just dismissed it. But after a week, It got a hell worse, before I even start-up my computer, the monitor doesn't show Analog/Digital at the top-left corner of the screen. PLUS my cpu keeps restarting after I pushed the ON button after 10 seconds or so.

My question, Is the monitor responsible for the restart and what could be the reason for the flickering?

Thanks for a fast reply.

Welcome Pokeman5 to the windows 7 forums.

The graphics card might be your culprit. Please update your system configuration settings under user cp so that others can maybe help you.
Usually the monitor won't stop your machine from booting. The graphic card most likely be the cause.

There is also the possibility that your power supply could be defective or going bad. Lots of possibilities.

Ok well, my computer is pretty old, but its not THAT old, it has always worked very well, and all of a sudden one day it froze and i tried turning it off but when i went to press the power button it wouldnt turn off, no matter how many times i pressed the power button. so i had to turn off the power switch in the back of the computer. it did this consistently so i decided to format my computer and delete the partition stuff like that, but it still did it, and i even virus checked and there were no viruses.

my computer freezes out of nowhere at random spots (startup, windows, my desktop, etc) and when i try to turn it off the power button doesnt work so i have to turn it off by turning off the switch at the back of the computer, please help me, i don't know whats going on!

Answer:URGENT PROBLEM: Computer freezes, but can not turn computer off

Try holding the power switch in for at least 4 seconds. There is a entry in BIOS for instant off and 4 second delay. Yours is probably set to 4 seconds. Delay is good as it prevents accidential power offs from hitting the switch by mistake.

If you are hiolding the switch in and it isn't powering down there are two possibilties. Switch is defective or connector has came off the header.

I am having trouble with a 6 month old IBM R51 laptop - when I select TURN OFF COMPUTER from within Windows and the START button - the computer sometimes hangs and will not shut down. I have to press the power button to reset. Any idea what could be causing this?


Answer:Computer Hangs When Turn Off Computer Selected In Windows

Welcome to BC! There are many possible causes, however there is one common cause. Often XP's exit sound file gets corrupt and if it does not run then XP won't shut down. I am not sure based on what you have told us so far if this is the issue or not, but let's see:Go to:Start > Control Panel > Sounds, Speech, and Audio Devices > Sounds and Audio Devices > Sounds tabUnder Program Events scroll down until you see Exit Windows. Highlight Exit Windows by clicking on it once. Then under Sounds choose None. Click Apply and finally OK. Reboot if possible, or shut down computer and restart manually. Once it is up and running, shut down computer by going to Start > Turn Off Computer. See if it will shut down on it's own now.If it does, the only difference will be that you will not longer hear the 2 seconds of music that XP usually plays as it shuts down.

Just got a new to me P3 computer up and running. Sometimes during star up it does not recognize the PS2 keyboard. Which makes it hard to go into my password protected User ID. When trying to shut down it will keep a few things running like some fans and the CD drive. But it does not sound like the Hard Drive is spinning.

If I use the XP to shutdown it goes into this limbo stage of neither off nor on, same goes for the power button on the front of the computer. It will either start up the computer or turn it to the limbo mode. Upon starting up, I can use the mouse to get it all the way into a non password protected XP users screen but can't do anything without the keyboard working. In the process of setting up I have had everything working earlier today but this keyboard and limbo status has been an intermitent problem. What should I try?

Hi all.
I moved out of a 14-year-old case (Gateway) and into an Ultra brand Gladiator mid-tower.

I have an EVGA nForce 650i Ultra Motherboard, and a "Power Up" brand 450-Watt power supply.

The setup worked fine in the old case, though Windows was freezing regularly after 15 minutes. I figured that was related to the hard-drive, since it wasn't tightly mounted, and I wasn't using enough cooling fans. So I got a new case and cannabalaized a fan from an old computer.

The power outlet and cord are good, and I swapped out the power supply with a 230 watt unit, and pulled the switch from the old case, but neither powered on the computer. Nothing seems out of the ordinary with the switch on the case I bought.

Did I buy a defective unit? Is there something I'm missing or should try again? Something else? Thanks for the help.

Answer:Changed computer cases, now computer won't turn on

Have you considered that going from a 450 psu to only a 230 might have something to do with it?

Is the motherboard shortening out by any part of it touching the case?

There also would be these little blue lines on the computer screen (Sometimes their would be alot of the lines and sometimes the lines would be made by the trail of my mouse).

- Rolling Back My Graphic Card.

- Updating My Drive from Windows Update.

- I've tried using a program that test my computer and tells me whats wrong with it. It said I got a problem with something like the VIDEO MEMORY CARD and I don't know what that is.

Is the Only way I can fix this is to buy another Graphic Card. I do not want to waste $200.00. Please Help Me!

Hello there, recently, I've been having an issue with my PC. Randomly, all peripherals (Monitor, Keyboard, Mouse, Speakers, etc.) turn off, but the computer stays on, and I need to turn it off by flipping the power off, and once I turn it back on, it boots normally and such. Like I said, the times this happens seem to be completely random, though I believe it has only happened at night, but that may be just coincidence. I have used virus scans, and nothing has come up, so I don't believe that's the issue. I haven't made any significant hardware changes recently either. Does anyone have an idea of what could be happening?

Get into the motherboards bios by pressing a key noted when you first power up the computer. Look for "hit F? for setup" or something like that. Reset the bios to defaults

So when I got home from work the other day my computer was turned off. (it is always on) I went to turn it back on and it will not turn on. Well it turns on in the sense that the lights come on and the fan in the back starts up but that only lasts for about 3 seconds then it shuts off again. After that it just keeps trying to start up but it's the same thing only for about 3 seconds. Does anyone know what the cause of this might be?

Hi guys,

I recently purchased an assembled computer from simlim. It was working until recently where i pressed the power button and the computer wont boot. The LED light on the motherboard is on and the fan wont move.

Tried turning it off and on in 5 mins interval several times but couldnt work. Tried testing the power supply also.

Any suggestions?

The specs that i know :

Processor : Intel core i3 @3.2 ghz
Video Card : MSI R6850 Cyclone IGDS Power Edition
OS : Windows 7

Answer:Computer cant turn on

How did you test the power supply?

Did you ensure that all power connectors are properly connected?

This is an issue regarding the power supply or motherboard. Since there's no POST beep code (is there?) or anything of the like, there's no other explanation other than these two. You will probably want to RMA it since you just recently purchased it.

The only way I can turn off my laptop is by pushing the off button on the upper left side of keyboard, I seem to remember that turning off laptop that way is BAD and can cause damage....true??
Anyway back to the problem, I click on the start button and click "turn off computer" then the popup shows "standby", "turn off" and "restart" I click either turn off or restart and nothing happens, the hour glasss shows for a few seconds then goes way and my background and desktop icons just sit there.
I recv this error msg when starting my computer, I go thru the "windows starting up" msg then the "welcome" screen then my desktop items appear then this error msg "error loading C:\WINDOWS\system32\ugicksnd.dll", access denied, it also says RUNDLL at top of error box.

I see there have been a couple posts like this, but thought I would personalize it.

To start, on my old comp I had problems with it turning back on when I turned it off. It would just come back on by itself.

Then one day it suddenly shut down, and would not turn on. When I tried to turn it on, it made a litle noise (would later discover it was the noise of fans turning on for a split second) but nothing else.

I figured it was old and I wanted to update anyway so I didnt care.

I went and bought a new motherboard, graphics card, processor, new RAM and a new power supply.

They were:

GIGABYTE GA-G33M-DS2R LGA 775 Intel G33 Micro ATX Intel Motherboard

APEVIA ATX-AS520W-BK ATX 520W Power Supply 115/230 V CB IEC 950/ TUV EN 60950/ UL 1950/ CSA 950

Intel Core 2 Duo E6700 Conroe 2.66GHz 4M shared L2 Cache LGA 775 Processor

GeForce 8800 GTX

And Kingston ValueRAM 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory

I installed everything into my old case.

When I turned it on the processor fan spun, fan on the power supply spun, and fan on the side cover spun for a second, then shut off.

I switched outlets and when I turned it on again, suddenly the processor fan and power supply fan both turned on and stayed on. However, the processor made a high pitched continuous noise.

I turned it off. I noticed the fan was a little loose from the motherboard so I tightened it and turned it on again. Again it turned on... Read more

Answer:New computer will not turn on

Even tho' 520w PSU should be enough, it may not have the needed amps on the 12v rail(s) to fire up the mobo.... hopefully that's all it is. My other thought is that maybe the heat sink on the CPU wasn't seated correctly and the CPU may have been thermally damaged. I know it doesn't seem possible that a CPU can reach critical temps that fast, but a friend burned up on old Duron 800 by turning on the PC for about 3 seconds without a heatsink; "I was testing my RAM and just wanted to see if would POST and didn't think I needed the heat sink..." - famous last words Double check everything: the RAM, video card, CPU, all power connections and data cables. Be sure everything is seated firmly. Maybe take the mobo out of the case and see if it powers up "on the bench". Maybe something in the case is grounding it.

Hi. Recently, my younger brother, told me that his computer could not turn on. So, the first thing I did was to check if it was his charger's issue. It seems like it wasn't. Then, I decided to try again with my computer's charger instead on his computer. Well, I noticed something. When I plug my charger into the power outlet, there would be a light to signal power is flowing. And when I plug it into my own computer, it stays on. However, when I plug the charger into my brother's computer, the light vanishes. Is there something wrong with his computer? Thank you !

Answer:Computer does not turn on

Sounds like his charger is bad. If your charger works, and his doesn't, it's bad.

Hi I have a really old computer from 2001, that just one day refused to turn on (I haven't done anything to it at all for years). As in nothing happens when you press the switch at all. I opened it up, and saw that the green LED on the mobo was still on. Does the green LED on the mobo mean that the problem is not the PSU?

All the cables are snug and tight, and everything is plugged in properly. I've checked that tthe switch works properly too. It just refuses to turn on. Could it be a problem with the PSU, or the mobo?

I think it's PSU problem rather than a mobo,so try with changing PSU,it's a cheaper solution to try...

Sounds like a Power Supply issue. Try to remove the power cable, wait 15 seconds so it can drain the power, move the voltage switch (red switch on back, you will need a pen or flathead) to 230, wait 10 seconds then move it back to 115. Plug in the power cable and test it.

Try to disconnect everything from your computer apart from the mouse KB and monitor remove the power cable then press the ON button for 30 seconds or so to discharge whatever power might still be in the system and let it sit for 10 - 15 minutes then reconnect the power cable but not anything else you disconnected and see if it boots. If that doesn't work there are other things to try but try this first. Also it's always helpful if you complete the details of your system in your System Specs section of your profile

I'm building a computer for my parents for christmas to upgrade their archaeic thing they call a computer and i put everything together and it won't start up. Everything is connected right to my knowledge and i think it could be a bad mobo. Its technically my first build although i replaced nearly everything when i customized mine, so i'm not completely ignorant. I thought it might be the PSU so i swapped out the 420 watt psu that came with my old computer that worked fine with the 350 watt psu that came with the case... same results- An interesting note both PSU's make a high pitched hum when the switch is turned on and the cable is connected. No juice tho. I have reseated the cpu twice, all the pins are straight- its my old cpu from my computer that i upgraded and it worked fine the day i took it out. I have checked all the cables to make sure they are secure, and the PSU is set to the proper voltage on the back. I'm stumped- i ordered all parts from newegg and the packaging was fine- no dents and everything was brand new. I removed the soundcard-and left everything essential connected and tried powering up but still nothing. Does anyone have any ideas on what i could do or what i havn't tried?


Answer:Computer won't turn on

Why dont you put all your specs so we might better be able to help.Did you put the motherboard in a new case.If so try to take it out with everything still on the mobo and lay it on some static wrap without the drives hooked up and see if it powers up.It could be grounding out on the case.

Answer:Computer won't turn on

Power switch or power supply. Watch the fan blades at the back opening of the power supply as you press the power switch. If they turn 1/4 to 1 turn then quit, it is the power supply.
Used ones for an old machine will work fine. About $5.00 Easy to replace with a Phillips #2 screwdriver, removing four screws, then unplug a few cables, plugging new ones in the same place.

In a nutshell, my desktop computer won't turn on anymore.

This is a system that I have built. It has been working with the current CPU and Motherboard for over a year. The last hardware upgrade I made was a new power supply and an extra stick of RAM, but it's been working fine with those things for a few months.

Last week, I when I was trying to plug something else in near my desk I somehow pulled on the other cords and my system all went off. I pushed all the plugs back in, and everything else powered on - speakers, monitor, etc. but not the computer. I wiggled the cables, unplugged them and plugged them back in, all that stuff, and it still won't come on.

I don't think it's the power supply because I noticed that when I flip the power supply's switch to "on" my optical mouse lights up.

I'm just not sure what else I can try or how to test what else it might be. Any suggestions would be helpful. thanks!

Pull the RAM sticks out and then power on.If you get beeps, that's good. That means your motherboard/bios is working and has detected the missing RAM.If you plug in the RAM and do not get a display, and do not get any beeps, the motherboard/bios is not working. One of the RAM sticks is bad, or you are not inserting them correctly and it's stopping the motherboard from operating..The three most important things in computing:1. Backups, 2. Backups and 3.

My computer has been working fine for about 8 months since I built it, and then today it randomly shut itself off. I unplugged it and let it rest (assuming the processor was overheating), then tried again and it does nothing. I've also cleaned the processor/heatsink and applied new thermal solution. There's no way for me to actually check the temperature since it won't turn on, but I'm pretty sure overheating is out.

Sorry for this odd question, but someone who knows a lot more than me about computers, told me that it's not good for a computer to be turned on and off a lot. Let's say, for example, I use my computer 5 times per day, and I turn it on and off each time, would it be better to leave it on all day, and just turn it off at night?

Any lights anywhere. Does the fan in the power supply turn only 1/4 to 3 turns? Can you boot in SAFE MODE?
CPU fan failure; One memory module dead; Video card dead; power switch failure; cable or wire to the board from power switch has fallen off; Some device in a PCI slot has shorted out, such as modem, audio, usb, or firewire card failure.
Let us know how it turns out.

First hello everyone. My problem is this. Just a few days ago I tried to turn on my computer and it seems like it tried to start up but went dead on me. I have taken the side panel off to get a better look at what was going on and here is what I notice. When plug in, there is a power light on the motherboard that is light up. When I press the on button, for a few seconds, the cpu fan, psu fan and case fan come on and then shuts down. Pressing the on button again will do nothing unless I shut the PSU off and turn it back on, press the on button once again and the fans come on for a short second. Nothing else happens, the hdd will not spool up.I have metered the power supply and there is 115 v going to it. Could anyone help me in trouble shooting this problem, thanks.Specs,The computer is about 6-7 yrs old.Intel 3.0ghz450 w power supplyWindows XP80 Gb hard drive1 Gb DDR2 ram

Answer:Computer won't turn on!

I am thinking age here - and possible failure of one or more PSU rails.I would wish to remove plugs on supply rails from their respective devices and see if all give feeds - looking for 3.3v, 5v, and 12v.  The mobo LED suggests I think 5v present but if something else is missing you possibly won't go beyond fans.Check this out first - seems you know how to use a meter, which helps.  If PSU is OK then maybe BIOS - wonder if BIOS battery has expired.

Computer will not turn on. Sounds like it is starting, but screen won't turn on and computer stops making noise, doesn't sound like it running anymore. But the power light stays on. Already plugged and unplugged all power cords and power strip, still nothing. Worked fine yesterday.

I've never seen it happen myself, but usually we just leave the computer on, so I wouldn't notice if it had turned on itself.. my dad, however, swears that sometimes he'll turn the computer off, it will turn off completely and stay like that, then later he'll come in the room and it's on. When no one else is home...

So is this like.. a bad power source thing? I don't know all that much about hardware problems...

I did a virus scan and spyware scan,
don't know..

I'm wondering if there is someone that has patience here with someone who knows hardly anything at all about computers. I was trying to install my norton anti virus but it wasn't installing properly so I tried un-installing it and re-installing once again. I continued to do this about 5 times and in the end gave up and turned my computer off. When I tried to turn my computer on the next morning all I could get was the "set up utility menu" . Any help you can give would be so much appreciated.

Answer:please help, can't turn computer on

Couple of questions:

1. What version of windows are you running?
2. Can you get into safe mode?

What do you mean by "setup utility menu"? What options are you getting?

My computer was struck by a power surge that came in through our cable connection. Now my computer will not turn on/post, basically no power at all. I know it probably fried the NIC card I installed, and since it will not turn on, I guessed it fried the MB too. Well, lucky for me, I found another Mother Board- same manufacturer and model number- Biostar M7NCD. (I know its old- lol) Well, I switched out the MB's this weekend, and still no luck. I did take care when installing, always being sure to ground myself before touching anything, etc. I then thought perhaps the power supply was to blame. So, I removed the PS, and tested it in another computer I know works. The power supply is working fine. The outlet I was using when doing all of this is working fine as it turned on the computer I was using when I tested the power supply. I also attempted to bypass the power switch on the tower by touching the two prongs on the motherboard with a small flat head screwdriver, still no luck- though quite honestly, I may have not done that correctly. I touched the two prongs that correspond to the power on/off switch, and I also did this with the reset prongs as well. Still no power at all.

Now that I know the power supply is ok, and bypassing the switch is not working, could this be anything else other than the Motherboard? I just want to make sure I am covering all my bases before I tell the person I bought the motherboard from that is was DOA.

Thank you for your help!

Answer:computer will not turn on

It could be that the CPU has been fried as well. Among other components. A power surge can take out anyhing attached to the power supply or motherboard.

I'd like to be able to click START, then click TURN OFF COMPUTER and have the TURN OFF COMPUTER window show up right away like it used to do.

Answer:Turn off computer

Why hasn't Windows XP SP2 been upgraded to SP3 - which was released over 4 years ago?

What's the model number of that HP Pavilion?
If you don't know for sure, advise what the product number(P/N) or model number(M/N) on the sticker is.

My business computer froze up on me tonight at work. I own a Liquor store and this is the PC that has my cash register software, prices, and inventory on it. I turned the computer off and when I turned back on I got nothing. I unhooked all my cables and tried again. Thinking it may be my moniter I brought the pc home and tried. Now when I plug it in and turn it on the lights come on, the fan starts to run and then a couple of seconds later it shuts down. Just like you unpluded it.
Any ideas?

Answer:My Computer will not turn on

Time to start troubleshooting, and, given this may be very valuable info, you might want to take it to a shop.
1. Check the outlet at work. If it starts at home it should start at work. Maybe it cooled off by the time you got home.
2.This could be a power supply or a heat issue. Clean out any dust/dirt and get the PS tested.
3.If you don't have a backup plan, now is the time to get one and implement it.

My computer won't automatically turn off, am using XP, go to shut computer off and it stops at a blue screen. Have to hold the button in for 10 seconds b4 computer turns off

Answer:Computer Turn off

Try a virus scan and use a program like "registry mechanic" to see if there are any problems in the registry!!!Also look at the "power" management to see if anything looks abit "iffy" (I know that last one is a long-shot, but you will never know!!!)

So recently my computer would not turn on. So I automatically thought it was either my psu or my mobo. Since I was already going to buy another psu I just went for it and bought one. I installed it, and upon pressing the power button it fired up, I was happy.About 3 minutes later, after I was already on the internet, it shut down again. I pressed the power button to try to turn it on and nothing happened.So I tried changing sockets on the wall for some reason, and it worked. Computer came back up, I checked the bios for overheating but I was running at 34 degrees so I continued starting up, only to find the computer shut down upon window's startup.I tried plugging the cord into a different socket and every time it fires up again for only 2 seconds now. If I dont change the plug then nothing happens whatsoever.If I leave the computer alone for long enough, then I am able to use it for longer without it powering off, which I would believe would be linked to overheating but the temps are completely fine.Any Ideas?Please

Answer:Computer Won't turn on?

Could be a short in the power cord.Try another one.

So about three weeks ago I was watching a movie on my computer and it crashed. It resarted and continued to run for a while but it crashed a second time and the second time I could smell what I thought to be burning popcorn and realized it was coming from the computer. Now I thought it was the power source since the power light on the computer would come on but nothing was turning on. I just installed a new power supply and tried to turn the computer on but all I got was the fans to spin for a second or two and after that nothing would happen. So basically I'm wondering if you think my processor fried or my motherboard? Any help would be appreciated.

Answer:Computer Won't Turn On

Hello and welcome to techspot!

It does sound like either a CPU or motherboard is toast. As a last resort, try the following:

1. Test some different ram in there.
2. Take everything out of your motherboard except, CPU/heatsink/fan, one stick of ram and your video card (unless you have integrated of course) and see if you can get into your bios.
3. Try resetting your CMOS.

Good luck!

My resolution is turned to the lowest. I'm not sure exactly why, is it an issue?

My video card failed not long ago, I replaced it (Nvidia 9800 GT) and when it failed one of the symptoms of it was the resolution turning low, but there were a lot of other symptoms and I haven't experienced them.

Does anyone have an idea why this is occuring?

My drivers are up to date, on Windows Vista, it's a Gateway computer.

Thank you for any help you might be able to give me,

I built the computer with all new parts about 3 weeks ago. It had been running fine on a daily basis. I get home one day and go to turn it on. I touched (did not press) the power button and it starts to power up, fans and lights come on but then it stopped and turned off. Now the power button does nothing. The light on the motherboard is on. If i turn the power supply off and then on the lights and fans come on and then turn off. I tried clearing the CMOS and nothing.

I am thinking I must have static shocked the power button and fried that part of the MoBo.

Any thoughts?

Answer:Computer will not turn on

Power Supply has gone bad? Borrow another power supply, or a power supply tester to check it out before you mess with other stuff. Having brand new power supplies fail is fairly common... and it is the first component to check.
New motherboards also fail. But I doubt what you proposed with the power button... They are protected from this unless it is a very crummy case.
After power supply, strip down to the most fundamental install... a floppy drive, perhaps, or another drive with a simple install. Disconnect everything. See if you can get something to run with just the power supply and a floppy disk or USB thumb drive.
Prepare a check list and run down all the possibilities as you go. Be sure to look for other failures that can cause this... bad memory, bad cpu fan, cpu fan not connected exactly right, CPU heat sink hold-down has slipped....
Do this with plenty of rest and a check list. Your enemy is frustration and panic. Just calmly go back to basics.
Good luck. Let us know how it goes.

Hi I was hoping if anyone can give me an answer to a problem I've been having.  I bought the Lenova Ideapad S10 from Hong Kong about a month ago, and it's been working great, until last night!  I fell asleep with it on for a few hours, and when I woke up, the thing was powered down and would not turn on!  When I press power, the led light the right turns on, but it's not blue (more like a purple color)  When it is plugged in, and when I press power, the two led lights to the right turn blue, but the thing does not turn on!  The notebook is relatively new, and the battery is new so Im not sure why it's acting up this way.  I've tried the method of pressing the power button 15 times and holding onto the power button, but when I plug it in after it still doesn't turn on.  If anyone can give me any input it'd be great.  Thanks!

Take out the battery and AC charger, and press the power button for 10 seconds 3 times, then 30 seconds a 4th time. Put everything back in, and see if it works. If not, i regret to say that you may be facing a shorted motherboard.
