I've been having BSOD's for about 30 days now. I've tried removing all the hardware in the computer except for the hard drives. I've swapped out memory, video cards, nic cards, and removing all USB devices. I'm running a fresh install of XP Pro (2 days old.) I'm getting Problem caused by a device driver. Latest error (5 minutes old) was Stop 0x0000008E (0xc0000005, 0xbf8ec8ae, 0b640cbc8, 0x00000000) Win32k.sys address bf8ec8ae Base at bf800000. I'm using an athlon 64 3000+ cpu Motherboard is a K8M800-M2. From this information can you please tell me if it's the motherboard or the CPU that's going belly up?
