Have a HP notebook that was dropped. Screen destroyed, but otherwise system works fine. Got screen replaced. Now the system will boot to a BLACK SCREEN with a MOUSE CURSOR only. SAFE BOOT same. SAFE BOOT with COMMAND LINE same. Tried booting to VGA resolution - same results. So I can't get to a UI to do anything. Tried Vista recovery disk, but there doesn't seem to be a way to reset the video driver. Have confirmed by replacing the system disk that the screen is fine (installed Windows 7 RC without a hitch on another disk as boot device. Would really like to retain/recover the original boot drive, but I can't boot from it until I can get the video driver to get stupid enough to handle the replacement screen (which appears to be same resolution as the original judging from the Windows 7 test build). Anyone know of a way to reset to the DEFAULT (generic) video driver on a system when you can't get to the UI for it?
