I had the same problem about a week ago, dude. I'm not sure if you've tried it already, but I had to uninstall (you reformatted, so that's pretty much the same thing) and unattach/reattach my video card. For some reason, I guess the connection was faulty. Give it a whirl, if you haven't. It's a long-shot, but no TF 2 would probably feel just as bad as being diagnosed with AIDS.
