I current have
Biostar tp67b+ motherboard
16g g.skill ddr3 memory
Windows 7 ultimate
I was using an old ati card from 2005 512mb DDR pci-e
I just purchased the Asus 6870hd directCU.
I installsd the card finally got the display to work, and installed the drivers from the CD that came in the box. After doing that it prompted me to restart the system.
After rebooting my system has slowed dramatically. One I get past the windows log in and the desktop starts to load I get a blue screen telling me somthing about the display drivers, Nd that it is dumping physical memory.
It sounds like something happened to the drivers when you first rebooted and they didn't install correctly. When I was using my GTX 460s every few months I'd get a driver error like that and have to re-install them. Hopefully this will fix your problems too.
Alright. Problem solved. I did a system restore, booted in safe mode with networking, went to the asus website and downloaded the newest driver. restarted and POW! I believe the drivers on the cd they provided me were bunk.
Thanks for all the input guys. This was starting to frustrate me
