- Step ONE, boot in save mode (hold SHIFT while booting)
- Step TWO, remove videodrivers & install the standard VGA driver (standard PCI GFX card or something like that)
- step THREE, try to boot into normal mode
- If step THREE works, proceed to install new driver
- If step THREE fails, you're registry is most likely ****ed up, make a backup copy of it, (scanreg /backup) and delete the ENUM key under HK_LOCAL_MACHINE (do this in save mode, beware, this will KILL ALL DRIVERS)
- If this doesn't work, that you really should do a new install
(To install without formatting, rename the windows & program files dirs, and delete or rename win.com)
