After a recovery of my XP Pro, I didn't find the normal basic low-resolution AVG display driver, this driver was a little bit different, and it didn't accept my normal driver. Looking for a way to change to the standard VGA, I found a drop-down list (with just two options) which I hadn't seen before, I took the chance of changing it. Then Windows restarted, and when Windows started, the screen was black. The bios display is OK, the booting process is displayed OK, until Windows start, I hear Windows is working, but the screen is black, the same in safe mode. Obviously, I have accidentally deactivated the VGA driver, or set too high resolution rate, or too high refresh rate?? This is a Catch 22, how do I reset this witout display? I looked into the Windows Recovery Console, I found a driver/service named VgaSave, may be this could be of help? Before I do this, or finally reinstall everything, I ask, anybody having a good advice?
