I have two video cards:
- XFX PVT84JUDD3 GeForce 8600GT XXX 256MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card
- EVGA 256-P1-N399-LX GeForce 6200 256MB 64-bit GDDR2 PCI Video Card
both running the same set of drivers on Windows 7 64-bit. When I work with 2 monitors connected to the 8600GT card everything works smoothly. When I connect the third one to the 6200 then Windows works well and all of a suddon the screens turns black for up to 5 minutes. Then it goes back and at some random interval it goes black again. I can still see the pointer and hit CTRL+ALT+DEL and see the menu to log off, bring the task manager, etc.
I've tried changing the 6200 to another PCI slot and the error persists. I've tried connecting 2 monitors only one to each card, same problem. Tried swapping them, mixed and matched the monitors to see if it was a problem with the monitor and my conclusion was that it is not the monitor.
The problem also occurred with Vista 64 as well.
What could be generating this problem? Can it be the fact that they are different interfaces? Maybe the Motherboard? Should I change something on the BIOS? What do you guys think?
