I'm running windows XP and my computer keeps getting stuck in a loop when I boot up. It asks me if I want to boot in safe mode but my keyboard will not work. When it times out it starts to load Windows but gives me a BSOD that is so fast I can't even read the error message. My keyboard does work when I load the BIOS or try toboot from a disk but when it asks me if I'd like to boot from the disk the keyboard stops working. I don't know how else I can access the computer to trouble shoot, please help.
