So when I put my 2600HD Pro into my computer, everything was fine and dandy.
But when I started to play some games, the skins and walls of the games would turn out to be green/purple pixels, the skin is purple with white stripes, and I was wondering if it's my graphics card, my drivers, or my mobo.

Well...any other indications that your graphics card might be bad?

Problems only when gaming?

Did you take a look in Event Viewer for clues?

Run the DirectX diagnostic? Which version of DirectX is installed?

It's an ATI product, so I guess it's probably the drivers (I have 2 old ATI cards installed) .

Are you using the drivers from the CD (not from the website)?
