I'm having trouble with my memory. I just bought an Athlon XP 3200, 400 FSB, on a Biostar M7NCD-Ultra. My memory is DDR PC3200, 400 MHZ. The problem I have is I have my CPU set at 200% in the BIOS, the same with my memory. My computer restarts whenever I play games, or am just online. When I play UT 2004, its quits and tells me of a critical error... I don't know what to do, please help.
