just out of nowhere here's what i've gotten more than once:

A problem has been detected and Windows has shut down to prevent damage to your computer.

The problem seems to be caused by the following file: nv4_disp

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

The device driver got stuck in an infinite loop. This usually indicates problem with the device itself or with the device driver programming the hardware incorrectly.

Please check with your hardware device vendor for any driver updates
