PC doesn't recognize 560ti (448 core)

Ok...so I built my own rig about a month and a half ago, and so far so good. But this morning I fire it up and its at 800x600 resolution (normally 1920x1200) and doesn't recognize the graphics card. I tried reinstalling drivers, but even Nvidia says a card isn't present.

Oddly, I was in iTunes today and it tells me Quicktime no longer exists either...

At 11:30pm last night my computer was working fine. Before I shut down, I waited for a Steam auto update to finish installing, so that could be part of the problem.

When I boot up, the Nvidia product name etc does display briefly before the O/S load screen. ExtremeTuner doesn't load anymore either. The card is a Galaxy.

If there aren't any suggestions otherwise, tomorrow I'm pulling apart the rig and reinstalling the card - but since it does mention the card on boot and my screen is still working at a lesser quality (the hdmi is plugged into the card, not the mobo), along with Quicktime's disappearance, I feel like there's something else wrong...

Are you using the latest NVIDIA WHQL driver Version 295.73 that was just released on Tuesday, February 21, 2012?

Amazing. That was it. How did my computer totally dump the old driver? Did Steam have anything to do with that? Even Quicktime works again. Bizarre.

Thanks a bunch.
