I went on vacation for 2 weeks, came back and started up my computer. My second monitor wasn't working so I started messing around and found out that my video card wasn't detected. I went to device manager and the only one listed is the onboard one. So I tried a system restore and that didn't work. Then I tried to download and reload the drivers but they wouldn't install because there was no component detected. It's a GTX570. I've seen some of the other threads and tried a lot of what they said but nothing seems to be fixing the problem.
