Running Windows 7 64-bit I updated my nForce 730i graphics drivers from Windows Update. After rebooting, the system blacked out on the Starting Windows screen. It restarted, loaded System Repair and automatically selected the latest Restore Point.
System Restore did not complete successfully. Your computer's system files and settings were not changed.
Details:
System Restore failed while restoring the registry from the restore point.
The restore point was damaged or was deleted during the store.
Running Startup Repair found no solutions, and I could not boot into Last Known Good Configuration.
