Two different GTX 560s not being discovered by Windows.

Mobo is a H77 Pro, I'm on Windows 7 64 bit fully updated with a 650watt Corsair PSU.

So a friend of mine sent me two used (working at the time he shipped) Gigabyte 560s in hopes that I could SLI them, unfortunately my mobo doesn't support that.

Anyways, I decided to just hook up one of them.

I uninstalled the drivers for my 470, shut down, and plugged in the 560. Two PCI-E 6 pins, just like normal, correctly seated, everything good.

I plugged in the DVI cord to the card, booted, and go a "no signal". Ok, weird. Plugged it into my onboard video and booted fine.

Went to install the drivers and got an error that said "compatible hardware not found".

It should be noted I had the exact same issue with both cards which seems strange considering they were both working at the time of shipping. They were also both packaged very safely and there were no signs of damage to the box.

Also, after re-installing old drivers and my old card, everything works perfectly normal.

These are the drivers I tried:

Well... the issue is not the motherboard because with the latest bios it should be compatible with the 560 (and even newer cards) and it's not the PCIE slot because your 470 works fine. It's not the PSU for the same reason (470 works fine).

I'd have to say the only way to make sure nothing happened to the new cards (BTW I also agree it would be very odd for both to have been damaged during shipping) would be to try them in another computer (that meets the requirements to run them)

Pretty much what I figured. Now to find a computer that they I can test them in....

Update- and I feel absolutely retarded about this but I just found this out.

Guy who sent the cards to me typo'd and they're actually 460s. Sorry about that. Shouldn't really change anything though right? I mean the computer should still display via my onboard if I boot with no drivers installed and the DVI hooked up to the card. Correct?

Not to "nit pick", but it would display via default OS drivers through the 460. Also, yeah it should not make any difference that they are 460s, they should work.

You're welcome. I hope you find out what the deal is with those cards. I really hope they weren't damaged in shipping (again I really don't think that happened either).

Just a little info from a problem I was helping someone else with. It's not exactly the same issues but the "solution" might be pertinent here. It turned out that the persons motherboard bios was just not ever developed to use NVidia GPU higher than the GTX 500 series. And even being aware of that problem, the manufacturers (DELL) never did a thing about it. It may just be that you mobo doesn't want to work with a slightly lower caliber card then what you already have... It's a shot in the dark but it's the only thing (other than faulty GPUs) I can think of.

Best of luck sorting this out
Cheers!
