ok, for no reason at all my computer restarts. sometimes it happens during boot screen. sometimes i can have it on for like 3-4 hours and it just restarts for no reason. it's really annoying.

i've tried re-installing the correct drivers. i don't know what else to do, im not a hardware person.

can anyone link me or give advice on how to fix the problem. ask questions if you like because i don't know what you need to know to  help fix the problem.
