Windows isn't seeing my second GPU.

post #1 of 11
Thread Starter 
System info:

i7 930
MSI x58 Pro-E
2xGTX 260 (not in SLI)
Windows 7 Pro 64
6 Gb Crucial 1600
266.58 drivers.

I have a dedicating folding at home box and after the CC I was switching my user info from CC to my personal info and when I was running -configonly my second GPU said it wasn't compatible, (it had been compatible for the last 15 months). After checking, the card is not being detected by Windows, but it is detected by motherboard and the PCIok light is on and the appropriate color. I have never run into this problem before and don't know how to start troubleshooting this. I card is present in BIOS, it just isn't there when I get to Windows.

Indeed. It is not present.

edit- I am loathe to swap the cards around to different slots as this whole mess is underwater.

No, sir. One GPU is present under display adapters, as being GPU0 in PCI bus 2.

Have you tried reinstalling nvidia drivers?

You might also want to try to connect the display cable to the 2nd GPU, see if it will show up in windows.

I have a dummy plug in the card. I would think that would suffice as far as a display goes, but I'll throw a dvi and display on it tomorrow, and try driver redo. Thanks.

If I didn't hear what click? The PCIe retainer? The card has been in the board for about 15 months.
