This is the message on the blue screen when I have the GPU3 beta client running and try to use the nVidia viewer. It also happens if I run, for instance, an online MMO, City of Heroes. Strangely, if I run the nVidia viewer without running the client the crash doesn't happen. The viewer runs but some of the info and background it would usually have is missing but it doesn't cause the error. Anyway, here's the message on the blue screen -
------------------

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 problems with the device itself or with the device driver programming the device incorrectly.

The number at the end there counts up and not sure for how long and can't do anything else but press reset. The file nv4_disp is a graphic driver.
