System Restore is my new best friend.
I was able to decompress the restore file from when I first put the PC in, extracted the video driver, copied to a flash drive, brought inside and put on a floppy. Then booted into DOS thanks to a Windows 98 Boot Floppy, and delted the old drivers, and manually replaced the new ones.
It works! I have 32bit colour again!
Pain in the *** though. Now I have to put the PC back in the car in 10 minutes before I have to leave for work. I still dont know what caused this, but I sure hope it doesnt happen again!
