New build EVGA GTX 770 2GB not recognised by device manager or nvidia installer

[spoonman82]

Hi guys gonna ask a question thats been asked before but cant find a solution that works.

Just finished a brand new build and everything is mostly fine. Boots no problem and im able to work away with the integrated graphics but for some reason my GTX 770 isn't being recognised by the device manager or the Nvidia installer. the driver installer doesnt complete and shows error message " no compatible hardware found".

Heres my build:

Asus Maximus VI Hero
Intel i5 4670k
Corsair vengeance 8GB ram
Corsair 750W PSU
EVGA GTX 770 2GB
Samsung 120gb ssd
2* 1TB seagate barracuda hard drive

THe motherboard is updated with the latest BIOS version. One of the 1TB hard drives is from my old PC but I uninstalled any trace of my old graphics card or motherboard before putting it in the build so there should be no conflict there. There is power going to the card, its fans spin up when i boot the pc so connections are fine i think.

Any ideas? its driving me mad at this stage.
Any help appreciated, cheers gang

Did you install all of the drivers for the motherboard?

Make sure you have both the 8-ping AND 6-pin PCI-e power adapters plugged into the card, if you haven't done so already. Also, do you have the card physically installed on the motherboard, but are using integrated graphics for display? If so, power down your machine, unplug any video cables from the on-board video connectors, and plug them directly into the graphics card. Then, power on. The resolution is going to be messed up, but that's because you haven't installed the driver yet.

In addition, ensure that you have the correct driver. Go here to find drivers: http://www.geforce.com/drivers
and make sure you choose the correct OS, including if it's 32-bit or 64-bit.

If that still isn't working, do the above, except using a different PCI-e 3.0 slot.

Make sure the GTX770 is correctly/fully seated in the PCIe slot. You should also have the card installed in the uppermost PCIe slot. That is always the preferred slot. If that doesn't work, try the card in the next PCIe slot. First slot could be bad on the motherboard.

Also if you are able, try to install the card on another machine (maybe a friend's) to double check that you didn't get a bad card. You can't rely on the fans spinning as an indication that the card works. It is receiving power from the PSU so the fans would spin regardless.
