7900GT or the Motherboard?

[Bruizer]

Okay, so i just put an eVGA 7900GT KO and an ASUS A8N-SLI Premium motherboard in my computer. So i decided to run 3dmark03 (to compare old scores) and it would freeze in the first test every time. So i tried to play BF2 and it would freeze in the menu. So i went into my bios and changed the speed of my ram from 400mhz to 333mhz. I just decided to try this because i run 4x512 sticks of GeIL Ultra DDR500. Loaded up and bam, everything worked. I don't understand. My old MSI board and 9800pro didn't have a problem like this. I run a San Diego 4000 plus so i know i can do 4x512 400mhz at 2t timings and like i said the MSI could do it. Is this a graphics card problem or maybe a motherboard bios problem? Time to update bios? Help! Please!

Do you have the NV4 Chipset drivers installed?

Have you checked for an IRQ Resource conflict? This is what it really sounds like to me.

What all components do you have installed on your System?
