Hi ive been running this mame pc for about a year now, it was my old main computer, athlon 4000, 2gb ram, 350w generic psu, 6800gt, sb audigy. Well for the last month it just shuts off in the middle of playing. Well now when I go to play I am updating my gameex list and it cannot make it through the full update without shutting off, I bought a new 120mm fan since the old was siezed thinking it prolly overheating. Well By looking it the diagnostic in the bios screen upon boot up im getting 57 degrees Celsius, Ive let it sit idle for about 10 minutes now in the bios and its climbed to a steady 63 degrees celsius, and thats without any tasks at all just bios. My cpu fan appears to be running full speed.. 3233 RPM . Is this a PSU issue or do I need to replace my cpu fan even though it seems to be running full force, or the cpu itself have something wrong that its not cooling? Im not sure.. its 67 degrees now ... thanks
