System Restore won't undo bios changes, but windows update won't do bios changes, so there doesn't seem to be a problem here.
If the video drivers create problems on your system, go back to the old ones! If system restore can't help for whatever reason, you can revert to the previously installed drivers from Control Panel/System/Hardware/Device Manager/Display adapter.
