Problems with an XFX 9800 GX2 and Windows XP Professional

[malt 2x]

I've installed the graphics card drivers, DirectX, and all the necessary motherboard drivers. For some reason, any game I try to start crashes immediately (the games that I've tried are Fallout 3, STALKER, and Call of Duty 4). Anyone have any information about this, or can anyone offer any help? Thanks in advance.

What's the rest of your system?
What PSU?

Well see, I had this system running great with Windows Media Center 2005, then I decided to reformat it and put Windows Professional on it, and now I'm having these problems. Anyway, here are the system specs:

PSU: BFG 650
Motherboard: Asus PK5C
Processor: Intel Core 2 Duo 3GHz@3.52GHz
RAM: 4GB Patriot PC10666 DDR3
I'm not sure of the hard drive brand or info because it originally came in a Gateway system. All I know is that it's SATA and it's 250GB

I'm using onboard sound and onboard LAN. Peace.

Any ideas?

Have you tried running your processor at stock speed instead of overclocked?
