i have a 425 power supply was suppose to be for a p4 and amd approved. i have a speeze fan with an aluminum copper core heat sink. fan runs at about 4300rpm. i think fan is a 80mm. i have 2 other fans in the case also. i dled asus probe and processor stays at around 134F. i have been able to get farther when it does try to render with the side off so thats what made me think it was heat. i have scanned for viruses and get nothing. but today i was trying to do a large mpeg and it would shut down after about 5 to 10 mins of processing the video with premiere. thank you for any help you can give me.
