Windows 7 Black Screen Flashes for 2 Seconds when Aero is Enabled

Hey all this is the basics of my rig:

Asus N80v
Nvidia 9650M Card
2.4 GHz Intel Core 2 Duo P8600
4GB DDR2 RAM
64 bit - Windows 7 Home Premium

I updated my graphics driver from Nvidia's page just recently so I could enable aero, however since then once I use an aero enabled setting, the screen will pereodically freeze up and then flash black for maybe 2 seconds, and then return to normal.

Also, when I run it in a basic setting, there's odd lines of pixels just flashing red whenever certain images are on the screen.

Note I ran a clean install from vista 32 bit, however I know my computer is capable of vista 64 bit if that matters.

Thank you,
Michael

Edit: Since posting this, the flashing has occurred at lesser intervals in regular basic theme
