why does my computer do this?

for some reason my computer has been randomly restarting
itself. i looked in control panel at everything and i
dont understand why this is happening.

Rt click MyComputer>Properties>Advanced>Startup and Recovery Settings
tab>Uncheck Automatically Restart.
This may give you a blue screen next time this happens and you can get
information which may lead to your problem.

your video card is probably causing errors and causing
the pc to restart. i recomend swaping out the video card
and see what happens.
