Well to be honest it's not really a problem not unless the graphics tempature is high is constantly crashing when playing a game or when you turn on CNN and see what BP ****ed up this time...
j/k abit about cnn and graphics card crash.
What you can do is go to the manufacturers website and see if there are recent new or stable drivers for windows 7.
To be point blank don't trust windows 7 update driver to make everything work and function properly, even microlost gets it wrong with certain hardware driver updates.
Try Nvidia's site first to see what driver can help, I wouldn't know first hand because I have been using ATI for the past 3 years now.
