Hey everybody, I've been having this problem for the past seven months. My computer just randomly shuts off every so often (usually happens at least twice in one week). I use it extensively (have gotten into the habbit of obsessively pushing ctrl+s), and when I first got it, I was pretty careless and would leave it on for days at a time.
I recently replaced the harddrive and am still experiencing the same problem. I have an Asus A7v600 motherboard with a wd800 harddrive now (used to have a wd raptor 80 gig).
I cleaned the fan and verified that the temperatures were normal, but it still happens. Any suggestions?
