Currently I have a gtx 260. The power reqs are similar to the reqs of a gtx 670. The gtx 260 works great. I installed the EVGA GTX 670 FTW 4 gb into the slot previously occupied by the gtx 260.
Upon boot all I got was a black screen.
I opted to connect my monitor into the onboard gfx card in order to see if the pci-e slot even saw the gtx 670. It did not. I put the gtx 260 back in and windows 'sees' the gtx 260.
Now, when the gtx 670 is in the pci-e slot its fan comes on, but then shuts down immediately. It's not a PSU problem (I have a Corsair TX750), because the gtx 260 actually demands more power and it works fine.
My question(s): does anyone have this card? Or a similar one. Did you disable the onboard graphics card through the bios? More to the point, what settings to do you have in the bios? And yes, I updated to the latest bios.
