dust can cause short circuits. Vacuum out the inside to keep it clean.
check your power source. Do you have heavy machinery attached to the same circuit? e.g. kettle? TV? etc., Starting those machines together can draw enough power to upset your computer.

Do you have an AMD CPU? It runs hotter than Intel.
Make sure you do not open the case to keep the computer "cool". Opening the cover will defeat the airflow design, and cause the CPU to overheat.
Quote from nkhoi:
if you have auto update, window will restart your PC
"Some updates cannot be installed or will not take effect until you restart your computer. For those, Windows notifies you to restart your computer for security maintenance. If you are an administrator for your computer, you can delay the restart; otherwise, Windows warns you and then restarts your computer for you." Could be hard drive gone bad, listen for any strange noise. Could be virus, try rolling back to the day before the probl started.
Restart on a blue screen (system crash) isnt a BIOS function, its a Windows setting:Quote from Cache Landing:
IT guy at work suggested that I check the BIOS setting for the auto restart on bluescreen error.
If it sometimes tells you to check the hard disk that means that it did not shutdown gracefully (which would rule out Windows restarting itself for an OS patch) - I would follow the suggestions for others about checking into hardware problems. Unless the PC is fairly new, you may be better off just getting a new one.Quote from Cache Landing:
A few times a day my computer will simply restart itself automatically. Sometimes it tells me that I might need to check the hard disk and other times it just boots up as if nothing had happened.
\Quote from GTS:
Restart on a blue screen (system crash) isnt a BIOS function, its a Windows setting:
Control panel->System->Advanced tab->Startup and Recovery (Settings)->System Failure->Automatically Restart (Checkbox)
Your BIOS likely has a setting that allows you to decide if the PC should remain off or restart automatically after a power failure
I would check the Windows event log to see if there are any strange messages that coincide with the restarts.

When in doubt reformat and install Windows again, that way you completely rule out software if it is still happening and can concentrate on hardware
