I have just bought a new case, and rebuilt my sons computer. The motherboard and processor are KT600-A motherboard and the AMD Athlon XP 2700 Processor. It is running Microsoft XP. When He is playing City of Heroes, the computer either shuts down or gives him the message "VPU Rcover AGP settings graphic framebuffer size. I do not know what to do. I think maybe I do not have something with the graphic card correct from when I put it back together. Not sure.Any help at all would be appreciated.
