I purchased an ECS K7S5A Pro board with Athlon XP 1700 CPU, 256 MB DDR 266-mhz Ram with the intent of using it as the base for a new computer I was building for a sister's friend. I have Windows 2000, installed it, everything seemed fine. However, when installing Norton Internet Security 2002 (or the W2K service pack 3 updte) it invariably gets to what it calls a corrupt bin file or somesuch and stops installation. It also can't seem to find the drivers for the video controller, the USB controller, and the PCI something-something (Yes, the lack of sleep shows doesn't it?). At first I thought maybe the cd-rom or hard drive was reading wrong, but the problems persist after getting them replaced with newer models. I know for a fact that the files in question are NOT corrupt, so I'm thinking it could be a hardware issue. For those who have the board, I have the CPU setting at 133/133 mhz on the CPU PnP Setup Page of the Bios (I've tried 100/133 Mhz but that drops the XP to 1.1 ghz and doesn't seem to be any more helpful than the previous setting). I've never had problems like this before, it's driving me crazy.
