What cable configuration do you have? If you are using a splitter, please consider swapping to using three of your GPU ports.
Is there an SLI bridge plugged in? If so, take it out. Your configuration doesn't support an SLI bridge. Make sure SLI is disabled.
Which version NVIDIA drivers are you running? Have you recently updated?
No power's not an issue, I've had this up & running before.
I downloaded the most recent driver for the 9600, I didnt do anything to the 9800 because I figured there was no need as it was working fine.
I'll take a look at the BIOS now & see if I can see anything.
You had this up and running before... and then it died.
I had my PC running for three years before my PSU faulted and took one of my GPUs. If your power is inadequate for the system, it will cause what is known as power sags
which will destroy the most effected device.
Over time, the capacitor aging gets worse and worse. GPUs in an SLI/CrossFire configuration are most likely to fault due to lack of power from capacitor aging, or stop powering altogether.
Though if you are confident your system is perfectly sustainable, it might just be a software issue.
Don't download a driver for your 9600. Head over to the NVIDIA website and download the latest NVIDIA drivers. The file for the 9600 or 9800 is probably identical, but to be sure download which ever is the latest for your 9800.
Uninstall all previous drivers.
If that doesn't solve it, your GPU is probably just not in the PCIe slot properly. Take it out and put it back in.
