What happened immediately before the memory dump, did you download/install anything? Were you connected to the internet? Otherwise check your physical connections, power and IDE (if relevent), then go to the BIOS on boot and see if the primary device is recognised.
3 times this weekend my computer had the blue screen on it saying it was dumping the physical memory.
Nobody was using it, I just saw the message as I was walking by. The first 2 times I rebooted, it started up
normally. The 3rd time it gave me a ''harddrive not found'' error. I am using XP sp2. The hard drive is
less than 6 months old. I don't have any extra hard drives, just a cd-rom & a 3'' floppy.
Any help would be greatly appreciated.
