OK, I'm really stuck so I'm coming to you guys for advice. My computer running Windows Vista Ultimate recently had 2 Blue screens of death. After the last one, I rebooted and my computer displayed an error message that I didn't quite catch, something about a disk not matching something. After that message, the screen would display a black screen when I boot, and it still does every time I boot. I tried a recovery disc and a boot disc with no avail. Anyone know what's going on and how I can fix this?
