Hey satchmo, listen i had a similar problem which i solved (after many many failures) that way: 1. Uninstall ATI drivers 2. Uninstall nForce drivers 3. Install nForce 4.27 drivers (and this one only!!) 4. Install Catalyst 4.9 drivers (again - this one only!!) those versions are the most stable for the combination of ATI GPU and nForce mobo. if you are unable to find the versions mentioned, i'll be glad to send them to you by messenger/ICQ etc.
