Not yet. Although I have done an OS repair. Have also found a thread on an AMD forum which suggests there is a problem using GeForce 6 series with the 76x series AMD chipset.

Thank you for your email. This is an issue which has been reported to us and have been able to reproduce. We are currently still investigating this issue and hope to have a solution soon for the next driver release. The bug since to appear in driver version 80.51 and above and affects only Geforce 6 family products on the AMD 761 chipset only.
At least there are a few more tings to try in that thread starting with the 7x geforce drivers.
