I have been on my pc for a while.. then all of a sudden it restarts itself. So I looked at it, it was still clean from last week and nothing was overheated. I start it up again.. and 30 seconds or so after loading windows and some other programs like winfox and msn etc... it shuts down.

Re: Auto restart without warning
Go to control panel>administrative tools>event viewer and look in the left hand listings at programmes etc and see if there are any red crosses or exclamation marks to give a clue as to the problem, but if you know it's not overheated and you have'nt recently installed any other software and recently scanned for virus and spyware it is probably a driver problem.

To reset it you should hold the power button until the pc shuts off. Then restart it and let the updates continue. If it still tries to update, just let it sit and finish. Do not restart it. It should restart itself. Worst comes to worst and it is bad still, post another msg on here and we can go into safe mode to turn auto updates off. Good luck!
Not without trying to narrow down the choices. If it shuts off like you turned the key its probably something electrical like a relay or the coil. But you would really need to troubleshoot it when it happens to narrow it down.
It may be possible that your CPU is overheating and the BIOS restarts your computer for safety reasons. You should open the tower and clean the inside of it. Unplug the cooler from the processor, clean the fan od the cooler, install new cooling paste on the processor and put them back. It should work perfectly. N.B: Do not change the BIOS settings. If you need further assistance, leave a comment. Cheers
If it starts fine when cold or will restart after it cools down and run until the engine warms up, have your TPS (Throttle Position Sensor) replaced. I have seen quite a few lately that will "warm" up and cause the car/truck to gradually run rougher as the engine compartment heats up and once it sits and cools off will restart and run again. You can go to auto zone, advance auto, etc and have them run a free diagnostic test on your car and tell you for sure if any TPS trouble codes are stored
Bad power supply; once it heats up will quit without warning
Bad heatsink/fan; processor heats up and will lock up your Pc
Try opening the machine and give the inside a thorough cleaning, paying special attention to the heatsink and fan. Once clean and you've ensured the fan is operating, put it back together and see if your problem is fixed. If not, a new power supply will likely fix your problem. Best of luck. Greg
please clarify this sequence of events:
"on AC power,it seems to be working fine. But the problem occurs when I try restart it on the next morning"... was it restarted next morning on AC power or battery...which one?
