As I was debugging a RAM problem with my system, I think some OS files
on my hard drive corrupted.
Thankfully I could get the system to load in safe mode, which allowed
me to pull off my files.
I considered letting BitLocker decrypt the hard drive and doing an
upgrade install of Vista, but I'm just going to wipe the HDD and start
from scratch. The decryption would take too long.
Anyways, I should be back to normal fairly soon.
