Go to guru3d.com and checkout the latest high performance drive for the ATI card and Vista. From guru3d.com you also check for the latest DNA driver for ATI. You want find better driver.

On other ting is the heat control on the card. Is the Fan (if have one) working?

Keep checking for new drivers from ATI.

I have an ATI X1300 video card with a Samsung monitor that pivots and I kept downloading the latest drivers because in Vista the UAC prompts would totaly black out the screen if the LCD were pivoted to portrait mode, but on 5/17/07 a driver version was finally released fixing it. I had had several revised video drivers before that magic one came out. Keep checking!

I think the Omega drivers are good for ATI videocards, especially if you're into gaming. You can find them here.

You should always run a driver cleaner when changing video card drivers. Files left behind can cause issues later, I've exprienced it firsthand. Read how to use it! it should be run in safe mode.

Unfortunately Driver Cleaner Pro is no longer free so you can't get it from their site. Some old versions are still going around, the last free version can be found here.

Rumor has it a new Vista service pack will come out soon which will have lots of fixes for graphics cards issues.

You can turn off UAC if it drives you insane. Given that it doesn't protect you from any exploits, I'd say turning it off is no harm right now.

Are you sure it's the video card and not something else? It might be overheating issues with the CPU itself.
