|I can't see how the sub would have any affect on the graphics card. Maybe the hard drive could be affected but I don't think the GPU. |
Be sure you actually replaced the driver. If the driver was corrupted and you installed the same version it may not have actually replaced the original one. Remove the driver completely and reboot. Then install the latest drivers.
If that doesn't work then most likely the GPU is damaged and needs to be replaced.
If the graphics are integrated then try installing an add in card.
