It this is the first time you've seen this Stop error screen, restart your
computer. If this screen appears again, follow these steps:

Check to be sure you have adequate disk space. If a driver is identified in
the Stop message, disable the driver or check with the manufacturer for
driver updates. Try changing video adapters.

Check with your hardware vendor for any BIOS updates. Disable BIOS memory
