Ok, I recently just built a system for my mother. It's using:
MSI K9N Neo v2
AMD Sempron 1.8GHz
1GB Generic DDR2 667Mhz

Now i've installed Vista Home Premium 32-bit onto the system, but it will not detect the graphics card at all. Although i have got a display (Motherboard does not have on-board).
I've tried using the driver disk supplied with the card, but it always tells me to go to the XFXForce website, so i do and download their drivers and install but CCC does not appear to get installed. I've tried the card in another Vista 32-bit System and it gets found and drivers install nicely and the card works fine. Is there anything wrong that i'm doing??

The other system runs:
ASUS M3A-H
AMD Athlon 64 2.9Ghz Dual Core
2GB OCZ Platinum DDR2 800Mhz

On the target system i also installed SP1 and still it made no diffence.

Any Suggestions?
