My computer simply likes to restart on its own for the fun of it. Whenever im running around 20 hours up time or so my computer will generally restart itself for no real apparant reason. However, I'm using an Antec P180 case that seems to me may have some thermal issues and a thermaltake big typhoon. I was wondering if this could just be a case of harddrives overheating or something of that nature, or does this simply sound like a ram problem?
