Lately my computer has been shutting off at random times. Usually it's while playing a game. My first thought was my graphics card was overheating, but I used to Rivatuner to monitor my GPU temps ingame, and they were fine. My next thought was the CPU was overheating, but I monitored that as well, and that too was fine. The only thing I can think of is that my GPU is under powered, but it hasn't been a problem for over a year now until recently. My system specs are below. Biostar Nforce 520 AMD Athlon 64 X2 6400+ 4GB Crucial Ballistix Thermaltake PurePower 500w XFX Nvidia GeForce 8800GTS Creative X-fi Xtremegamer 1 250GB boot volume 3x750GB in RAID 0 DVD-RW drive I used a PSU calculator to calculate how much power I needed to run this hardware, and it said around 560w, but that doesn't make sense considering it has only been happening once in a while, and not until recently. My computer use has not changed. Thanks, Tony

Hi Tony, A friend of mine is having similar issues with his PC. I don't know what your issues are but he hears a clikcing sound on his PC and then it shuts off. The clicking sound can be his hard drive. Do you hear clicking sounds before your PC shuts down?

No, there is no clicking.
