GeForce 570...working terribly PLZ HELP

When ever I play games i am getting an extremely distorted image. There are odd polygons and lines on the screen that flicker on and off. I have no idea what is making this happen. The only upgrade i have done recently is changed out my old Geforce 9800 card for the new 570. This problem also happens with any internet browser (I've tried IE, Firefox and Google Chrome) With the browsers the edges, particularly near the Minimize, Maximize, Close Window part int he upper right corner becomes heavily distorted, however when I move my mouse over the distorted image it immediately goes back to normal. I have enclosed the following video of me trying to play a game, I am getting 60 FPS so performance isn't' an issue but rather the distorted graphics. http://www.youtube.com/watch?v=w5bPhtKiZ4s&feature=yout...




I have a Dell XPS 720 http://support.dell.com/support/edocs/systems/xps720/en...

The basic specs are:
Intel Core 2 Quad CPU Q6600 @ 2.4GHz
4gb ram
GeForce 570
Running Windows 7 (32 bit)

I was running 64 bit and thought that may be the cause of my problem and rebooted to the 32 bit to see if that helped... it did not. This problem happens with EVERY game I play from Age of Empires III to SWTOR. However, when I'm watching a video (either on DVD or from the internet) the picture quality is perfect.
