Computer will not turn off

Question: Computer will not turn off


It has just recently started to happen but when I log off, it goes through the motions as normal but instead of turning completley off it just goes to a black screen and sits there and the power to the tower is still on and the only way I can shut it down properly is to press and hold in the button on the tower. Here is a log of my HiJackThis if you require it.

Preferred Solution: Computer will not turn 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.)

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.

After that pop-up message, the computer freezes for about a minute and goes back to its normal format (desktop) and the computer DOES NOT TURN OFF.

How do I turn off my computer without unplugging the computer? I try "ctrl+alt+del" to go to the windows task manager to "shut down" the computer but..the computer restarts again and doesnt turn off. Do I have a virus or a windows explorer problem? and how do i fix it? thank you

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.

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

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.

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.

Answer:My Computer monitor doesn't show anything when I turn my computer on.

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.

Hi everyone,

While turning on my computer the it turns on, fans are starting to move, but screen won't turn on, and the beep of the bios is not heard.

pressing the sleep/reset button next to the turn-on button computer goes off, pressing it again turns on the computer without any problem. (now I'm working with the same computer) i thought maybe it's the power supply that gives me problem but changed between computers, this still gives me trouble and other computer works good (besides its many problems ). any idea what to do?

Thanks in advance

BTW, while trying to write this thread I got all this terms that i didn't know how to call in English, like power supply - is that the box which connects to the power and to all the m-board and drives? is there an English computer terms dictionary?

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?

- 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.

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?

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?

Thanks in advance

Okay, so this is a little embarrassing, but my desktop won't turn on. It was working fine yesterday, so I opened up the side panel and after blowing out a little dust, making sure things were connected, I tried again. It looks like the power source is working just fine as there's a light on it when it's plugged in, so I don't think it's the problem.

Answer:The Computer will not turn on

Hi Allen,
Welcome aboard, Not much to go on but if the problem was off and on before and it does do something now [faint humming] I would say the power is getting to the primary of the powersupply at least and the problem could be in the secondary&rectifier section or the connections between the powersupply and the devices it supplies. Someone will have to open the case and do some checking.Power supplies are not very expensive and a loose connection shouldn't be too hard to find .
Good luck, Bob

Any ideas? other than the Mobo is dead?

Answer:Computer won't turn on

If you are getting no fans or anything when you hit the power button the first thing I would look at would be the power supply. Do you have access to another that you know is OK, that you could swap in to test with. If you do test, do it with the minimum possible hardware (CPU, 1 stick RAM and Video) just to see if it starts powering up.

Check, then double check that all the cables and connectors are securely in 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!

Answer:Cannot turn on computer

sounds like a short in the connection to either your walll or to the powersupply. could be a faulty powercable.. seems like the most logical thing, try using another cable to connect from your pc to the wall. if that doesnt work, its a problem with the PSU or wall outlet. you can test the outlet with another device to eliminate that.

I have a second computer which has a 478 chip,video card etc. For a longtime I have noticed when I go to and run pcpitstop it says my video card is performing badly...56 pixel while the average is 124.

Recently it wouldn't start properly and my monitor would flicker and die so I changed the monitor but got the same problem.

I had already changed my power supply so I took it back and asked if they would check my video card.

They said they had found a problem with my motherboard and solved the problem.

Although it starts up ok initially, after about 15 minutes it blacks out .

However the thing is still going even when I try to turn it off with the switch.

If I hold the switch in, it does go off after about 15 seconds, but when I let it go it immediately starts again but nothing appears on the screen. Eventually I get it going again and it boots up perfectly only to crash again within 10 to 15 minutes.

Answer:My computer won't turn on

you probably just didn't hook everything up exactly the same. the easiest part to mess up is to reverse the mouse and keyboard if they're both the PS2 type and one isn't usb. The next easiest to mess up would be if the PC has onboard video and a card and you put the monitor to the onboard connector instead of the card. Really take a close look in the back and quit messing around inside, you didn't change anything in there for her cleaning did you?

Okay well my computer has been taking an age to start up for a while now but no matter what I searched for I never found anyone with a similar problem on other forums and thus could never find an answer. I can't really afford to go get it repaired right now so I've just been living with it for months; essentially I get the initial splash screen, the windows loading screen and then blackness for ages! Sometimes the screen is black for a good six to eight minutes, then a little cursor appears in the centre and I'm brought to the screen where I can pick which user I want to log in to. From there it's all fine.

Ever so often though, the computer just hangs at the black screen forever, so I have to power it down with a hard reset, then restart and a menu comes up after the initial splash screen asking if I want to run startup repair. Whenever I do that it seems to get me back working again (still with a very long boot time) but it will uninstall either Google Chrome or ITunes. I don't think it's because either program is the problem, I think it's just cause the updates get corrupted when I use the restore manager to reset back to a prevous working state of my computer. Either way, I re-install them and they soon work fine and dandy. My problem is now that the computer won't turn on at all.

Okay, about two days ago, I decided to thoroughly clean my computer, in and out. I kept a log on which connection go where so that when I put everything back i dont screw anything up. The majority of the cleaning was with just blowing air or lightly wet cloth for the tower. Only thing i didnt clean was teh power supply cause i didnt wanna bother opening it but i cleaned the vents.

After I put everything back together i let it dry for a while and tried to hook it up that same day. As soon i plug in the power supply to the wire, high pitched noise came and later a funky smell. In response, I immediately disconnected it. I thought maybe its still needs to be dried up, so I left it as it is overnight. Next day I try again. Same thing happends and this time, same noise happends. I try turning it on and it didnt. I checked all my connections, everything seems to be in place.

What went wrong?!?!? Whats is that high pitched sound?!!?

The PSU cant be broken cause i was working normally before i cleaned it.

Answer:Computer won't turn on!! Help!

Sounds like something is/has shorted out, where does the noise come from, if its the PSU its possible that it has failed, and will require a replacement, if it came from the PC speaker, then check you have everything wired correctly.

Well my friends last night it happened the unexpectable: after I defragmented my Hard Drives (which I make once per week) and I cleaned my Recycle Bin, I re-started it as I always do. O.K., then it appeared from nowhere a medium size black color rectangle occupying around 1/3 of my screen and the mouse didn't work properly, I mean the arrow was very erratic and I couldn't even to point it out the "Start" buttom; so the only option I had was unplug everything from the wall (actually from my dedicated Sub Station), hoping that any problem will be cleared afger that re-start.But after I connected the PC back to the Substation and I pushed the "on/off" buttom of my console nothing happened, it just did not work at all.

I have a dell dimension 4500 with a Pentium 4 , 1.80 GHz Processor and I wanted to upgrade.I went to my local computer store and I bought a Pentium 4 , 3.00 GHz (Btw I showed them my computer and they said that the Processor would be compatible)So I go home and install the processor in my computer(I was wearing a ESD wrist strap) I turn my computer on and it didn't turn on, so I take it thinking I just bought a bad part and I put my old processor back in and It still won't turn on!!The light comes on the power button and on the mother board, NO fans come on ,NO beeps, NO nothing.BTW I've tried two different power supplies.

Answer:computer will not turn on...

Did you seat the heatsink properly and put compound between the cpu Heatsink. Could be the fan did you make sure you connected everything back.

I am new here and hope you can help. My friend has a computer that the power supply went on so I replaced it and booted the computer up was running ok. Turned it off. Next time she went to boot it up NO POWER. I have tried another supply and it works but have not replaced it as the power supply I tested it with will not fit in the case. I will get another one. But I do not understand how 2 power supply's can go like this. Help

Answer:Computer will not turn on

Leave the case open and shutdown the computer and let me know if there is a green light (LED) on the motherboard and if it is lit even with the power off.

Then plug the one that is in the case back up now and see if it strangely is working again?

Hey guys, interesting topic isn't it? My dad has this computer, well I have NO Idea how he did this, but he set the computer in such a way that when he goes to Start > Turn Off Computer > Shut down the computer shuts down into a sleeplike mode. I can see the mouse is still on, but the computer is half shut, it's still running cus you can hear it.

When I hit a key on the keyboard, the compter starts up. What is this, sleep mode? I never used any of these options such as hibernate, so I have no idea how it works. How do I turn this off? As of right now the computer is at half shut down or w/e it is. Any help will be greatly aprreciated!.

Answer:How to turn off the computer?!

if you tap the power button it should turn off. if it sleeps again, then there's probably a setting in the bios that made it do that. reset the CMOS and then see what happens

A couple of days ago I turned on my computer as normal, it started up, made the usual beep sound, but then I realized something wasn't right.

After switching it on it came to the usual start up screen with packard bell on, then I waited and waited for over half an hour but to no avail ? I'm just wondering what is wrong with it, it has never done this before.

Any help or guidance would be grateful.

Many thanks

Answer:Computer will turn on but won't


Try performing a checkdisk repair and fixing the master boot record. Boot the computer to your windows xp cd and follow the on-screen instructions. When you get to the main menu make sure to choose "R" for repair. Then the computer will take you to a black prompt screen which is the recovery console.

The computer will ask you to choose the operating system so I believe, choose #1 for c:windows. The computer will ask you to type in an administrator password but simply press enter to skip the process if you don't have an admin password.

Then type in "chkdsk /r" and make sure there is a space between "chkdsk" and "/r". This process should take about 1hr to 1hr 30min. After the checkdisk repair has been done, type in "fixmbr" to fix the master boot record. Then after that type in "fixboot". Fixmbr and fixboot should only take seconds. Restart the computer and see if your computer is able to boot up.

Hello. I'm having a very weird issue with my laptop. I put my laptop into standby when I was using it earlier because I was moving it from one location to another and I was going to be using it in the other location. When I tried to power on my laptop, it wouldn't power on! Nothing was wrong with the laptop when I had used it earlier; I was on the internet with it and I even used it during one of my classes at college. I tried holding down the power button for a minute without the battery or power cord in, but nothing! Is there anything I can do?

Hi, my computer won't turn on. It's weird, i've tried to diagnoise it, but can not come to a conclusion of where the fault is.

I have been usin my self built amd dualcore/asus mobo computer for several months now. Works perfectly very stable with no problem.

The other day when i was usiny my computer, i suddenly smelt this burning smell from my comp, it immeadietly turned it off. I looked inside, couldn't see where was wrong, so turned it back on. A while later the smell came back, then my comp just shuts off, and will not turn on again(no twitch wat so ever when i press the power switch).

I opend the case and had a look inside, the onboard fans seem to twitch for a second when i press the power switch, but thats about it.

I suspected it was PSU problem. I had a new skyhalk 500W psu lying around so i plugged it in. Same deal as before, but however this time, the fans(cpu, mobo, vidcard) will spin up fine as long as the power is not plugged into my SATA hd. As soon as power is connected to my SATA hd, nothing moves at all as before(when i press power switch ).

So i go pull out a old ATA hd from my other comp, and plug it into this dead comp, now everything spins up, but still i can not get my bios/mobo screen to load up(monitor no signal).

Can anyone suggest what possibly could be wrong? is there a chance that the mobo or cpu is dead? but why would they just die for no reason, i mean if it always has been working really well and i have never touched the... Read more

Answer:Computer won't turn on, HELP!!!!!!!

Never heard of Skyhawk, which means it's GARBAGE. Yes, 9 chances out of 10, it is your PSU, and I would replace it as soon as possible, because it can (if it hasn't already) fry your other parts.

Get a quality brand name PSU.

I have a Dell Dimension 5000. For the last few months I have intermittently been unable to switch on the p.c. The first time it happened the button I press turned to flashing orange instead of green and pc wouldn't power up. Even when i disconnect it from the mains the power button will still remain lit as orange for a while. I put it into the local repair shop and when they pressed the button it started first time. They checked everything inside the p.c. but could find no faults. motherboard, fan, power unit etc working fine. Cost me 60! I've turned off hibernation , stand by etc. If i leave the p.c. for several hours it will switch on. it's really frustrating. Does anyone have any clues what has gone wrong?

Answer:Computer won't turn on.

I had a Power Supply that acted like this once.It's impossible to deduce what may be the problem, many different parts might cause it - you'll only find out by substitution. Try unplugging the PSU from the motherboard, and firmly replacing the connector first - then try another PSU."Even when i disconnect it from the mains the power button will still remain lit as orange for a while."That's normal - it usually takes a fair few seconds for the power from the PSU to die fully away.

Hello, I'm not sure if this is the right place to post but here we go.

I recently (last week) bought and built my computer that you can see in my specs on my profile, and all worked and worked well. Now, I'll be honest, I was running the computer for a 2 days with no system/case fans running. The stock case fans didn't work. So when my PC died while I was using it, I assumed it was heat damage to my CPU. After it died, it wouldn't switch on again. I would press the power button and nothing would happen. It was as if it wasn't connected to any power at all. However, the PSU's power switch LED is working and it powers the USB ports. This I have tested. So as far as I can see, its not the PSU. And the fact its powering the USB ports via the motherboard would lead me to assume that is working fine too. The GPU and HDD have nothing to do with powering up the system as far as I'm aware so I have assumed they work fine too. So I replaced the CPU today, but still the computer will not power on. So, its not the CPU's fault... I now ask you all if you know of any parts that could be causing this or any solutions to the problem. I have considered that it may be the power button but it wouldn't explain the mid use shut down I don't think, also I don't have any idea how to test it.

Note: I never ran any temprature checks during my short use of it so don't ask for tempratures, but I did have the side of the case off and the temp... Read more

Welcome to TechSpot

Did you put the memory back in its original place? Press it down all the way, so that both white clips slot into the openings on the side of the RAM-stick?
And if you added RAM, is it the exact same type?
Did you switch off the PC and disconnect it from the mains, before you pulled that old RAM? If not, you probably blew that RAM and is no longer useable.
Try it with only one stick.

I've just gotten the last part (The RAM) of a new computer that I was building myself. I put everything in its rightful place (I think), and I've gotten quality parts as well... But my computer won't turn on.

When I hook it into power, the light on the motherboard goes on, so I know it's getting power, but when I press the power button, the light goes on on the front of the computer, but the computer doesn't come on. A fan in the back flashes on and off (LED fan) - it looks like it's getting power for a little and then not... But the light on the mobo stays on the whole time... Aaaaggghhh - I've checked every connection, etc.

Any idea what my problem could be?

Well thats encouraging to start with, if your not sure if you did something right, then start from scratch, check everything is seated correctly and that the front panel wires are in their correct place on the board, make sure that the hardware such as video cards are working OK and that the RAM is the right type, make sure any jumpers on the board are in the right place, especially if you have one that resets the BIOS to defaults, some mobo makers leave the jumpers in the reset position.

I have a bizzare computer problem.

When I tried to turn on my computer, the power light came on momentarily and then shut off. I opened up the case to investigate and shut off the power supply and turned it back on. The motherboard stand by light was illuminated and I proceeded again to try and turn on the computer. Both the CPU fan and Video Card fan momentarily fired up and then shut right down again. Nothing.

I have detirmined for certain that it is not a power switch problem, or a power supply problem.

I'm assuming it somehow motherboard related or there is a breaker that has tripped somewhere, but I have no idea.

Any suggestions, cause I am stumped. HARD.

I have an Acer Extensa 4420. It's a really old computer, but it has been working up until about 2 months ago. I had put it away in storage due to not having a need for it anymore. (It was a bit slow.) Well, I went to turn it on one day, about two months ago, and it simply wouldn't. Now, this pattern does change. (I have the cord hooked to it to ensure that it is not the battery. The charging light comes on.) Sometimes the power button will turn green and then instantly blink back off. More often, though, the power light will turn on, the fans will start whirring, etc., and then it will shut back off. It will then turn back on, as if rebooting itself, and then shut off entirely. During, this process, the screen never turns on. There are times when pushing the power button will not turn the computer on at all.
The screen on the Acer is beaten up. It appears as if there is a nick in a small black cord on the right side of the computer that connects to the screen. I just replaced the screen about a year ago, though. I have also already tried to reseat the ram modules by popping them out and putting them back in. This did nothing. I then tried replacing the CMOS battery. This also caused no change. I did put electrical tape on the nick in the screen cord, but I don't know if that is even helping much at all.

I have had my IBM Aptiva since 2000 with Win98SE. Never ever let me down, although the OS has, more often than not. I never used the hybernation feature until recently. It didn't work that well, but still I used it for half a dozen times. Everytime It came out of hybernation it would power-up with the hybernation window on the desktop and then go back into hybernation. On second power-up it stayed up and worked as usual. BUT, two mornings ago it failed to turn-on. The two LEDs just flicker.

No HDD noise, no CPU fan, no PSU fan; nothing but the short flicker.

I diassembled the PSU, cleaned it and looked for fried items or burnt smell; nothing. Was unable to test voltages as I do not have dummy load. Internal fuse had integrity and managed to read +5V on two internal leads. As all failed, I reassembled the unit and had another go. The PSU fan worked and thinking all is well, reintalled it. BUT, same problem again. Computer won't turn-on.

Any help is very much appreciated. Thanks!

The computer is a Compaq Presario 5000. It has a Pentium 4 and windows XP installed on it. Im not any sort of computer-wiz but i do know a little about electronics. A couple months ago, my friend tried to install a wireless card into the tower. after that, she said the monitor wouldnt turn on. so i put off working on the computer for a while because i thought it was just a problem with the video card. well turns out there is more to this problem than i thought. for some reason, dont ask me why, she told me she had to take out the power supply. she dropped a screw in it. ohh man. and now, as soon as i plug the power supply into the wall, the computer tries to boot without me even pressing the on button. the hard drive lights blink as well as the power light on the front and also the cd drive blinks forever. the processor fan turns on as well as the power supply fan. the problem is, it doesnt sound like the hard drive is spinning at all and it sounds like the power is pulsing a bit.

sorry, i tried to describe the problem to the best of my knowledge so if you have any other questions just let me know. please help!

Answer:Computer Will Not Turn On! HELP!

a BIOS setting decides whether or not to automatically turn the system on when AC power is applied (it's a post-power failure setting).

I don't know how you drop a screw into a PSU... lol but you need to get it out so it doesn't cause a short circuit.

but anywho.. he's what you should do. You don't have to remove the mobo from the case (although that is the best way)...

1. unplug all power and data cables from the mobo and all other components
2. remove the CMOS battery and if equipped with one, set the CMOS jumper to clear
3. remove all RAM and PCI/video cards
---at this point there should be nothing but the CPU and HSF attached to the mobo---
4. blow out any dust from the RAM, PCI, and video card slots

Ive tried doing everything on here and nothing is working. I used my computer last night turned it off and now it wont come one at all. It sounds like it's trying to but won't. Ive only had this computer a year and it has only been used to put my pictures on it and movies... What can I do... I can't lose all my pictures of my kids ?
