I was playing WoW after I had installed some new drivers from nVIDIA's Site, restarted computer, and got back on. It seemed that now my screen flashes with red/green lights. Starts off with alittle, then get's more & goes faster. After it goes to fast with alot of the flashes, my computer freezes and restarts.

Is this a known bug or something I can fix?

EDIT: Eh, I guess I fixed it. I just re-installed the driver's.
