You might be interested to know that people reading these forums do appreciate the use of things like punctuation and proper captilization. Things are much easier to read when you can tell where sentences begin and end without straining to do so. I gather from your post that this has only happened once. However, it's a bit early to tell you what, if anything, is wrong. It could be Windows acting up on you, it could be that your card is overheating, or you have a bad video card. Can't come to a conclusion over just one event though (unless said event is the video card catching fire, then you can be damn sure what's wrong). There are a few things you can do to narrow it down. Try different games, different drivers, and open up your case's side panel to bring more air to the graphics card, maybe even point a fan at it. Don't do all three at once though; have one variable at a time.
Well, I wouldn't say "normal", but I wouldn't say "something to worry about" quite yet either. It could be a very intermittent issue, so keep your eyes peeled for the next couple of days.
