I have a 1.33gb AMD, running with Asus board, 256mb DDR ram, ATA 100 20gb Hard Drive, Nividia Geforce 3, Sound Blaster Audigy, 350w power supply. Well that is the system and the problem is I will be working on it and BAM it just restarts. No warning nothing just black screen and restarting. It does not slow down anything just restarts. Any suggestions? Running as a test PC it is not on a domain just single. Seems to be happening after I installed the new video card "Geforce 3". I am going to go into the bios and select the options when lose power remain off to see if it is a power problem but does anyone any suggestions?
