Computer wont display when GPU is installed?

[andrewgrady]

Hello, so I've recently swapped cases and motherboards with one of my server computers since it was getting old. But for some reason when I attempt to boot the computer with my old GPU, no display will go through. The only cable that is connected is a Display Port cable directly to the GPU. If I disconnect the GPU and plug a VGA cable directly to the mobo, everything works fine. I grabbed my main GPU from my primary computer to see if my old GPU possibly went bad, but even that one doesnt work. I am getting proper power to the GPU as I can see the fans spinning and the light come on. I checked in the bios and made sure that it was set to use PCI ports. I even tried using both PCI ports and still no luck. Any ideas?

Spec List:
Motherboard: MSI Z97s SLI Krait Edition
Processor: Intel i5 4690
RAM: Corsair Vengeance 8GB
GPU: Geforce GTX 770
PSU: EVGA G2 550W

Have you done a CMOS clear/reset?

Just reset it, still no luck.

Have you installed the drivers for the new board?

Have you installed the drivers for the new board?

Yes, just double checked and their all installed.

Please double check that all connectors are delivering the proper voltages. This can be done with a multimeter.

Here is an image of CPU and PCIe power connector pinouts.

If you have had a GPU recently in your PC the drivers may still be installed on the PC if you didn't uninstall them. For e.g. if you had a GTX 750 ti Drivers and put a GTX 970 in, it may try and load the 750 ti drivers. Its just because I have heard people have the same problem and they put their old GPUs in or use integrated and uninstalled the old drivers put the new GPU in it works. So hope this works.
