Hi, about a month ago my Pc started to restart itself, once every 6 hours or so, but now it sometimes restarts every 10 mins or so, i had this problem before and my Pc was overheating, but it isn't this tim e as ive checked, it usually happens when i try to do something big or load to many things together, i dont know if its my RAM or what? ive got two sticks of ram and ive tried switching them round etc but it still happens, ive disabled windows automatic restarting about 5 minutes ago so ill see what happens then, any ideas?
