Helping people with computers... one answer at a time.

A virus scan and checking the cooling fans in a computer are good places to start if your machine shuts itself off frequently.

My computer is turning itself off after about 5 minutes. Why?

Well, there's not really enough information to go on here. I'd certainly start with a virus scan, but another possibility is that the machine overheating - I'd check the cooling fans as well.

i got a similar problem. one of my pc's keeps restarting every 5-10 minutes. the strange thing is, it doesn't restart when you're in dos. I say this because when i install windows98, the installation goes smoothly. but after the installation, when it boots up in windows, it restarts or hangs. I boot it up in dos and after 3 hours, it's stable enough and doesn't reboot.

Tested all parts (memory, Processor, power supply, Hard Drive-no virus) and even flashed a new bios, but it still reboots in windows. Could it be that the integrated video is malfuntioning? the board has integrated vga/sound and i got no way of affirming it coz the board has no AGP slot. Got no PCI vid card and am hesitant to buy one. but if i do, would this fix the problem? Thanks again!

Shutting down itself and before that massege comeup that you is shutdown because window NT Authority.

With that error message you should be looking at things like the sasser virus. Start here:

For the person who asked the original question, it might be as simple as the power setting.
Right click on the desktop, go to screensaver, then power settings. There should be many different options.

try isolating the issue by borrowing a video card, memory, and proc. run your computer with only the 3 put in your board. put in all three parts that you have borrowed in your board (of course include the KB and mouse.

if the board works, replace one part, let's say your video card. and run your computer. if the computer does not crash or restart. turn it off.

now put in another part, and so on. this would most likely isolate the source of the issue.

i had the same problem ........ my pc kept restarting over and over again .. at the end it got stable after i uninstalled all the programs i had .... try it

I have a similar problem. Occasionally when I turn my computer on it just automatically reboots. And when I'm on the internet it reboots itself occasionally as well. Although when connected to the internet, I have managed to pinpoint when it is going to reboot itself. On the internet icon in the bottom right corner, when about to reboot, it only recieves bytes and doesn't send any. This can be resolved by clicking on the refresh button over and over again until some bytes are recieved. But obviously its annoying because I don't spot it everytime.
Could this problem have anything to do with my PC's slow processor at 400MHZ? Is there a certain speed of processor a computer must have to be able to handle broadband properly.

September 10, 2004 11:19 AM

I've just installed win98 on a hard drive I just fdisk, partitioned and formatted. Everything seems fine but it keeps crashing when I try and load anything....Drivers, new programs etc.

It was'nt working very well before, same problems,
crashing when I installed most games etc. That's why I cleaned it out and started over........can any one help me.
Thanks jdub2000

I have the same problems aswell, my pc is bout 7 months old and was workin perfectly b4 i installed another 512mb ram. I have 1gb of original ddr400 ram. when i had 512mb ram it allways worked never restarted, but now when i power up it goes past the bios and just about to load up the desktop, then restarts every time. Could it b tht my 2x 512mb ram are different makes? 1 is Infineon, and the other is hynix. but they are both original ddr400, coz when my pc starts up it says "Dual Channel Enabled". Please help me because i really need my pc, and i feel tht its quite good aswell.

October 5, 2004 11:01 AM

Well, you've done most of the diagnosis yourself :-). Looks like a memory problem to me. I'd grab memtest86 ( ) and see if that reports anything specific for you.

October 14, 2004 3:00 AM

I'd recommend you check all your cooling fans, might be a broken CPU fan so you computer shuts down of overheating.

November 18, 2004 7:16 AM

Hello, My pc was working fine before.
About a week I got disk error message on the screen. I have tried to press Ctrl+Alt+Del to restart as it asked me. However, not any luck. I have reformatted again and istalled windows xp pro on it. It works fine but now it turn off by itself about every 20-40 minutes. I have no idea what is going on wrong. I know I don't have any virus on my machine bucause I scaned several times. Help if you have any idea.

My pc was working properly for atleast 2 yrs. For the past week my pc freezes. I was told that the fan need to clean it is not working. I knew that the fan was working so I clean it. Presently my pc shutdown after minutes, sometimes seconds after booting up. What do you think is the problem

February 25, 2005 2:07 PM

hi im anita.I just got my pc not to long was working find until i started getting all of these viruses and pop-ups.i did a virus scan and it found about 9 and on today feb.25 my pc kept on re-starting about every 5 minutes ive been trying to fix this but it doesnt seem to be workin can u help me?

March 21, 2005 10:03 AM

i have the same problem... only thing i can think of that might have caused this is if you opened your computer and maybe didn't or improperly ground yourself before handling the equipement. the hardware is very sensitive to static and that could be what is causing malfunctions...if this is the case i don't even know how to find out what needs to be replaced

April 2, 2005 9:49 PM

Hey, I have excacly the same problem but i think what is causing this problem for you all is the bropia worm. It ussually swapps ur left and right button .. and sends unknown files to contacts on ur msgner. Search bropia worm on google. May help?

May 29, 2005 10:54 AM

I have the same prob But My Pc turns on and off for about 5 seconds nothing on the screen nothing its just keep turning on and offevery 5 seconds

May 29, 2005 3:17 PM

That sounds like a hardware problem ... most likely the power supply but it could be other things as well. I'd take it in to be looked at by a hardware tech.

July 3, 2005 5:21 PM

My NEW PC was fine until suddenly when I go to play games, after 10 mins it turns itself off. I think it was caused when I tried installing a modem and even after unistalling it still turns itself off! I've got no idea what to do!!! HELP ME

July 15, 2005 6:46 AM

Ok well, i dont know how much this is going to help.. but some of you that are using WindowsXP, try going to Control Panel => Power Options => And in the "Power Schemes" tab ... about half way down it says, "Turn Off Hard Disks:" make sure it doesnt say 5 minutes or 10 minutes.. it should be set to "Never" This way your hard drive will not shut down after 5 minutes. I dont know if this helps anybody, but i hope so, please let me know if this worked for you.

July 16, 2005 1:00 PM

My computer is having the same exact problem, it turns itself off after a few minutes of being on. weird thing is I disconnected my ethernet cord from the back of my computer and restarted it normally, it did not shut off at all. I then plugged my cord back into the computer gave it 30 seconds and shut off, someone please email me or repost a post here if you know any idea's what this could be.

July 25, 2005 4:46 AM

my probleme is like that: when I play a game or a powerpoint file, my computer is blocking (dark screen whit a strange noise) and i have to power down by myself.
I have xp sp2, intel pentium 4 1.7, ge force nvidia 4 mmx 440 128 mb, and a hard drive of 80 gb free

August 12, 2005 11:28 AM

God damnit! My damn computer wont let me play games. If I dont play games it will stay on all day, but if i turn a game on after about 2 minutes my computer just goes off and i cant turn it back on without unplugging it firts. i really need help PLEASE SOMEBODY!!!!!!!!!!!!

August 13, 2005 8:56 AM

sounds like you're having overheating issues. check your motherboard bios for temperatures. typically cpus should run around the 60's and lower. your system temperature should be about the 50's. and your video card should be about the 60's or lower.

August 18, 2005 10:42 PM


August 18, 2005 10:46 PM

Well, I'd check what the article mentions: the power supply, but also perhaps run a memory test: . If those both turn up nothing, my next suspect would be your motherboard.

September 9, 2005 10:48 AM

READ HERE FOR SHUTDOWN PROBLEMS! i had a q-tek 550 w power supply which i finally found out was giving me shutdown problems. my pc started turning off for no reason and i couldnt turn it back on till i upluged it from the wall, and even then if i tryed to turn it back on it would come on for less then a second and then go off again. u would have to uplug it, then plug back in again, then wait 10 minutes till pushing the power button, then pc would turn on?? but all seems well so far with buying a new power supply which is a q-tek 500w big fan version power supply, so i would say try changing your power supply if my infomation applys. good luck !! :))

September 24, 2005 1:59 AM

Thank you Chakaone ! I'm going to listen to your instructions and buy a new power supply, any good website for me too buy them off

btw i live in the Uk

October 12, 2005 1:40 AM

my computer had similar problems:
350Watt power supply
AMD 2000 Athlon XP
Aopen Geforce MX 4000 v64
HDD, DVD-RW and CD-rom plugged in

Computer worked fine whilst playing DIVX movies,
but as soon as i started a 3D game (HMM4 for example) it simply turned off by itself after 10-15 minutes with no BSOD. After an immediate restart it played another 5-10 minutes...

I checked power and temperature:
5V actually gave out 4,8V
CPU temp were 67/68 C

So it seemed to be CPU cooling problem.
I manually under-cloacked the CPU to 1800+
(from 133MHz down to 120 Mhz)
and it seems to work fine after 30 minutes playing. So it might be a "fix" u can use before
replacing the cooler. U also need to make sure that your cooler is well placed over
the CPU die and there is enogh (BUT NOT TOO MUCH - on the die ONLY, not around ;)) thermal compound on it.

October 21, 2005 3:04 AM

helppp !!! my computers switches ON ny itself.its so bad that I have to switch off the main power of the computer.however,when I try to on it,it switches off once it reaches the windows xp pqge,or sometimes even earlier than that.what shld i do!!!

I try to restart it again and again and it didn't last long until the computer turn it off again or I starting to play or click at FARCRY icons. Since I click that L button during gameplay, it seems to cause a problem ever since. Anyone who know the answer please help me!! I have been trying to solve the problem for two months now and I still couldn't solve it. Please help!! Thak you very much!!

November 17, 2005 9:38 AM


Whenever i run Biran Lara Cricket on my system, it sayd Computer Clock speed is approximately - 1880. It is below the required speed of 200 MHz. I tried changing the CPU clock speed but it doesnt work. Please tell me what should i do?

November 19, 2005 2:13 AM

My regular computer kept freezing forcing me to reboot. After about 15 minutes of repeating this annoying process, the computer works ok before shutting down and then rebooting by itself and shutting down again (this is more likely to happen if I try to go on line too soon or start running programmes) Eventually after about 40 minutes the bcomputer works brilliantly and goes on forever untill the next day when I switch on the cmputer and go through the same fun and games.
However I have now tried a more powerful replacement processor which did'nt boot up at all and now I've tried a new fan and heat sink resulting in an alarm sound and a sole screen message which tells me that the cpu fan is not working even though it is followed by switching off. Finally Ive put the old fan and heat sink back on and the message is still the same.

November 21, 2005 12:03 PM

the other day while i was playing Battlefron 2 my computer started to act weird, the mouse wasnt responding(wireless mouse) and then my computer died. But all the fans that where connected straight to the power supply worked. My intuition is telling its my motherboard but i want to make sure it is b4 buying another motherboad please help!!!???

December 15, 2005 12:22 PM

Please help, ive not adjusted any settings or changed the way i use my X.P but it's started shutting itself down,when idle,and an alarm sound comes from my pc. The only way i can reboot is by switcking it off at the wall and rebooting,wich is fine,but if i try to shut down and then restart,the same thing happens. i haven't got a clue as to whats going on. My pc is clear of viruses and trogans and my fan does work, but there is now way the pc is hot enough to crash as its not on long enough. Can anyone help???

December 29, 2005 2:36 AM

my computer was switching itself off. after a little while, but in the end i noticed that the hard drive cable was stoping the cpu fan.

December 30, 2005 11:28 PM

I recently built a new comp. nd i turn it on and literally 5 seconds l8r it shuts off ... i have no idea wuts goin on ... i need help ...

January 3, 2006 3:42 AM

alot of these problems seem to be related but the best help i can give is for all you pepole to get mother bord moniter but i will have to check my computer for the program you need to tell you what you mother bord model and make is so that you can see if there is anof power going to your system to find out if the 12v is around 11v it is ok but if it is lower i have no idea if the -12 v is around -11v it is ok and so on for all the others i not shure off hand what the core v are spose to be but i hope this helps

February 13, 2006 9:32 AM

I recently build a system. When I turned it on,
it gave the motherboard intro, and started to do its post process, then turn off after 2 or 3 seconds. It did this everytime, I turned it on. Before this happened though, I had realized that I had forgotten to apply thermal grease or gel on the CPU. However, at first, I did not think that was the problem. I checked all cables, and wires to make sure they werer connected properly and connected to the right sockets etc. Nothing worked...I turned on the machine, and it went off in 2 or 3 seconds again. Being stumped, and running out of alternatives, I took out the CPU fan, and felt the was extremely hot. I let it cool, and applied a little thermal grease on the CPU and reinstalled the CPU fan. Presto, the computer did not turn off, and I have been using it ever since. Amazing what a little thermal grease can do!!!

March 12, 2006 7:46 PM

Thank you

March 23, 2006 9:57 PM

check for the settings in the BIOS about power management that might be the cause of your problem, or Try changing your power supply to test if its working or not.

March 29, 2006 7:20 AM

I am having the same problem he is having, except it is happening during a my spyware/adware scanners. How would I change the power supply?

August 27, 2006 6:18 PM

hi, I just got finished upgrading a graphics card on my computer so i could play a certain game. My computer worked fine until i upgraded the graphics card and now, my computer last about 30 seconds after i turn it on, and then a "no input sign" appears on my monitor, and then the monitor goes completely black. The wierd thing is that the computer stays on because i can hear the fans still running, so i have to hold the power button until it turns off. I have been dealing with the problem for a while and i am very curious as of what is going on. Hopefully you can help.

November 22, 2006 5:53 PM

December 10, 2006 8:25 AM

ehh check if your computer is overheating. Especially if you have just bought a new hard drive. oh and clean off dust from the fan that might help too. Or a thermal compund on your processing chip might be needed.

Hardware. Could be motherboard, power supply, RAM, expansion cards ... pretty much anything. Probably time to take it to a technician for repair.

January 16, 2007 10:04 PM

I have had experience with computers restarting by itself at random times. Usually its a recent change in hardware. One example was with a Gateway computer, where I installed 768MB of memory, where the motherboard could only handle 512MB. After removing the excess memory, problem solved. I would check the manufacturer of the motherboard (or computer) to see if there is a BIOS update, or driver updates.

Or there could be a nasty virus. Use some free online virus scanning programs and see whats what.

March 9, 2007 9:48 PM

sometimes when im in the middle of doing something, my pc just turns off or restart. sometimes it doesnt do that. the first time that ever happened i found out that i had a virus then i got it fixed & now its happening again. but is it possible i got a virus ? how can that be i already installed an anti-virus protection !!!

March 21, 2007 12:54 PM

When i try to copy a dvd or play a game on my pc it turns itself off, but it only seems to ever happen when im using the cd drive. I have tried virus scans which have found nothing and i havnt changed any hardware inside the computer. Any ideas?

June 8, 2007 8:25 AM

My laptop turns itself off randomly. Its been sent back to the company and "repaired" it had a new fan, but its obviously nothing to do with the fan as its still doing it. It happens about once a week and the only way to get it back on is to remove the power cable and put it back in again, then the fan blows out really hot air. Its definitly not a virus. Can anyone help me please?

My PC is turning itself off minutes after turning it on. It's not on long enough to open anything as it does not finish loading before switching off. it can't be the fans as at most it only stays on for 90 seconds. Anyone got any ideas or should I take it to a repair shop?

My computer keeps turning itself off every 5 minutes and every time I cut it on again it takes shorter and shorter time to cut off until it just won't cut on at all. Then I let it sit for a few hours and I can go through the routine again. I vacuumed the fans, but now I don't know what else to do.

January 29, 2008 3:06 PM

First thing, unplug your machine. Then, I would suggest taking everything off the motherboard to include any extra video card, sound card, phone modem, etc, also unplug the wires connecting to the A: Drive (floppy), CD/DVD drives, and Harddrives. Then after you have that done take the small (watch size) battery out for 15 seconds or longer. By taking the battery out of the motherboard it resets to default. I would plug the machine back into the wall after plugging the monitor and keyboard and mouse into it. Start it and hold the F2 or whatever the systems screen says for setting or setup. If while you sit on that for 10 minutes it shuts off during that time it means its your motherboard. Sorry for that bad news... If you call the manufacturer of the product you have and ask for the replacement cost or repair do it. If they cant I would ask for a model of replacement and they are and will sell you it cheap. Yeah a same or better model. Unless its new Id just take it back to the store and get your money back. But anyways I hope this helps.

Hard disk,motherboard,power unit has been checked and it run perfectly well overnight at the shop. It worked o.k. for a few weeks but now it has started all over again. The techy in the shop can only advise that a full recovery looks as if this will be the only solution. Do you have any other suggestions???

Hi My Computer Turns Of Every 5min after I Tried Removing Something Called Anti-Virus-1 Now I Cant Do Nothing Without It Turning Off Do You Know The Problem And How To Fix It? Thanks

May 26, 2009 4:52 PM

Reply to: Posted by Dan at June 28, 2004 9:32 PM: For the person who asked the original question, it might be as simple as the power setting. Right click on the desktop, go to Properties, screen saver, then power settings. There should be many different options.

Reply: Thank you, Dan!!! I took your advice and yes, it was a simple solution. I right clicked on Desktop, then clicked on Properties - Screen saver. In Monitor Power at bottom, clicked on Power. Therein lay the problem! All four settings were set to turn my computer off after a designated time. I did not choose these settings. Bought this computer new in 2005 and the "turning itself off thing" had NEVER happened until recently. I'll probably never know what caused the setting changes. A similar thing was happening with my sound. The sound would cease .....then I discovered that the Volume Control was sometimes muting itself or the SW Synth Volume was sliding to the bottom .....or both! Again, have no idea why! I now keep a Volume Control icon in the Taskbar for convenience if it mutes again. The icon must have scared it because the volume hasn't turned itself off in a looooong time. :-) Again, Dan, many thanks for your suggestion! ~Joyce

Check you CPU temperature, if you set your laptop battery bios cpu temperature protect as 70 degree, when the CPU temperature over 70 degree, it will close.

Maybe you need to change your CPU fan.

My computer turns on an dworks fine for about 5 minutes. Then it randomly switches itself off. The fan is working and it isn't a lap top. I've checked the plugs and power supply. 5 minute sisn't enough to run a virus scan or delete any programs please help asap!

Read the article. It could be a virus or an overheating problem.

Same problem with me. My computer suddenly shuts off every 3 - 5 minutes. I already changed brand new power supply but same happens.

My computer screen goes black and the CPU won't turn it off. I have to unplug it which I know is not good for it. I just replaced the cooling fan a few days ago. Now the screen won't stay on,
