I've recently upgraded to an HD3870. Install seemed to go fine (Catalyst 7.11). Card functions fine in games and benchmarks (17,365 3dmark05, 11,447 3dmark06). However, every time I restart, I get a new device prompt, Windows detects a new PCI device, and wants to install. I just cancel out of the New Device wizard and its fine, but it is annoying. I can't figure out what device Windows thinks it has found. Any help would be appreciated.
