Windows 7 lock-up with XFX Radeon HD4650
Tearing my hair out over this one. I upgraded my Dual Opteron system from XP to Win 7 Home Basic. I have just added the XFX Radeon HD4650 graphics card (AGP). I Installed the drivers from ATI and the card shows up in the Device Manager. Problem is this: Whenever i start the machine normally, i can work for about 2 or 3 minutes, then the display locks up. Fully locks, no way to restart other than shut the system off. When I restart in safe mode everything works just fine. The device manager still has the drivers loaded and the system works fine (other than i am in safe mode and other things don't work). I have taken the card out and tried a different card in the PCI graphics slot, and that works no problem but i don't have that slot available, i really need an AGP card. I have also disabled all the things that run in msconfig on startup, but that didn't help. I also tried removing all the other add-in cards in the machine and that didn't help. Ideas?
