Driver?

It could be a graphics driver issue.

You should create a Backup Image of your PC and then try installing a new graphics driver (assuming one is available from the manufacturer).

I prefer to use Macrium Reflect Free Edition.
After you install it, create a Recovery CD/USB.
Then create your Backup Image.
Make sure you use the Verify option or verify the image after you have made it.

If anything goes wrong, you can restore your PC using the Backup Image
