Hi xXxexpertxXx, your temps are fine, but both the video card and power supply can and will cause random reboots if they are failing. Since it's easier, the first thing I would check is the video card, borrow one to swap in and test. If you get the same issue try a different PS. Earlier this week I had a video card that would work fine up until Windows started, then would either reboot the computer or go to blank screen with 8-10 scattered artifacts. I thought I was losing the HDD, but a quick video card swap stopped all the problems. Don't wait too long on getting a replacement PS, a failing power unit can take out other computer components. Mike
