Slight 2900 problem

[Deception]

I recently purchased a 2900 and finally put it into my system today. Well went well or so I thought lol. In games now, I get slight texture errors and games like BF2142 just go back to the desktop when I try to bring up the server list or go into the audio options. Ive tried the 7.8 and 7.9 drivers, but nothings changed.

I did the artifact scan with Ati tool and it seemed ok, then I tried it again like 3 hrs later and got artifacts straight away. I even tried another GPU test program and got no errors with that. If anyone has any input on this, it'd be most welcome!

*Edit* Also nothing has been overclocked and the rest of my system is:
Q6600
2gb PC6400 Crucial Ballistix
Gigabyte P35C-DS3R
Corsair 520W

That psu is more than sufficient for that system as im running my system off the same one without a hitch. Sounds like a driver issue rather than a card issue did you install a fresh copy of windows on this new system?

Yes, it was a fresh copy of Windows. Ive been through driver versions 7.7 to 7.9 now and its all the same.

I cant seem to get a program that will show me the GPU temp too, everest wont pick it up and neither will ATI tool.

Temps seem fine, it ran through 3Dmark06 and scored 11k, I guess thats ok. I guess it may be down to drivers or something then..

I was wondering could it be due to playing old-ish games on a new card, that there could be some side-effect or something?
