hmm guys having this prob ever since I've installed Vista. Wasnt able to detect my 4870 and my M2a-VM has an onboard GC which I've already disabled. Problem is it shows code 12 (conflict with another hardware which I need to disable) at the device manager list yellow "!".

I further installed a Northbridge driver(not knowing what this is) from ATI and it starts popping this error msg "Unable to find the correct driver for this hardware". Installed the latest driver still the same. Check the list again, still not showing 4870.

Reformat back to XP, problem solved. Craving for DX10 and less-crashing-os-vista but this is preventing me to do so.

Any advices?

Do I need to install Northbridge drivers? Whats northbridge anyway...
