My Computer Keeps Restarting Without Warning
Does your computer restart without any prior warning? You do not need to worry about this. We have the solution for you. This problem could happen at many levels. So lets start step by step.
Are you able to boot into the OS? If yes then at least your “Restart Switch ” isn’t getting short. But could be a super sensitive switch or a bad power switch too which creates the problem.
Now check if your computer is set to standby/sleep after certain time. Maybe it has problems going to sleep and can’t wake up, or restarts upon awaking. Disable this in your OS as well as in the BIOS (if there is an option).
If above two are working then its time to check the power supply. Here goes a small intro of how the power supply works.
If the voltage from the wall outlet or from within the power supply [faulty power supply] falls outside the tolerances required by the computer, the computer will reboot. This happens because the power supply constantly sends the motherboard a power-good signal, for example, if the power supply cannot maintain outputs that are within tolerance, the power-good signal is withdrawn and forces the system to reset. The system will not restart until the power-good signal returns. The power-good signal may be absent for a second or less, but that will still force the computer to reset.
This point has to do with proper power being supplied.
Check your wall socket for proper voltage. If you have the computer hooked up to the same line that goes to heavy power draw devices, such as an airconditioner, microwave oven and so on, does your system reboot when one of these devices is running? If so, you may need to change the outlet that you use or may need to run a new line to your computer, dedicated to the computer.

You will probabaly find that you have Gremlins in you PC. Us extra heavy duty Bug spray to solve the problem.
Or maybe your Moms turning it off while your not looking,if so then roundhouse kick her to the back of the head to solve the problem.
Otherwis leve your PC switched off to solve the problem

My computer Keeps restarting with out warning.I could be surfing the net or checking my email or playing a game and it just restarts.I only changed the Fan on it because thought it was over heating but wasnt the case the temperature would be at 45 C not a problem I think. Also put a fan in front of my case with out the side screwed on and it still restarted on me. It wouldnt happen when I had it pluged in a socket.I have a Anti Virus and I always scan for viruses and nothing appears. But need an urgent response quick.

Anyways. i better go, it will restart any second now.

It is most likely the PSU. If you’ve added things to your system or you PSU is old, then it could be under stress and/or about to go completely dead.

i just recently got this computer, and all the sudden it got really slow and it restarts when i am on the internet, it only takes about 5 to 10 minutes in between the restarts, but i have to get it fixed because i am a writer and i am currently in the middle of writing a screenplay so it has to be fixed soon with a low cost. i think it has something to do with MSN (Windows Live Messenger)

Its the virus activity and need to reinstall your windows. For temporary blocking of restarts of your system disable the McAfee agent running on your system.

this computer only started restarting randomly recently, and i dont know how to fix it. i noticed it happened after or during the time i installed internet explorer 8(is it possible to reinstall 7?), or when i was setting up this wireless network. i dont know if it has anything to do with those or its the settings on my computer, that i dont think i ever changed. i just want it to stop so please help.

I had the same problem!
I noticed the wire that hooks up to the power button was loose. I simply pushed it back in and the random restarting stopped.
Hope this works for some of you.
