I have a 64 bit windows 7 on a 3 year old dell gateway dx4831. I lost one screen, uninstalled the video card driver, and the computer stopped booting. Afterwards, we tried multiple cards, and the computer still doesn't boot, so the card is not the problem.

It gets as far as the opening animation, then it briefly displays a bluescreen and reboots. When booting in safe mode, the computer crashes at "AGP440.SYS."

 

The onboard video driver doesn't work, even with no card in the slot. It's greyed out in the Bios options. We've also reset the Bios.

I have the original install disk, and I've tried startup repair, checkdisk, and "sfc /scannow". I cannot do system restore, as it was never turned on.

Even with restore off, I heard that there was a hidden system registry backup. I can boot into the command prompt through the CD Room or through Windows Startup Repair, so we can look into the computer's files, but I can't start the computer. Can I restore the registry backup?

One may be able to restore the machine to last known good configuration by accessing advanced boot options > press F-8 at boot and choose last known good config.

If system restore is disabled; this may not work but one never knows....
