That's why we never trust these "Drivers" utilities.

A couple of options to try;

1] In Safe Mode, try a System Restore to a date/time either before deleting the drivers, or further back before installing SP3. Using the latter will mean re-updating to SP3.

2] If that fails, back to the Safe Mode list of options and try the "Last Known Good Configuration" option. it is similar to System Restore.

If both fail, can you extract those files from that backup folder? If so, copy them to the Desktop whilst in Safe Mode, top option), then head over to the Device Manager, find your video display and run the Update Drivers from there, but point to the files on the Desktop.
