Well, about 2 years ago I upgraded my whole rig. I purchased an intel i7 2600k and a Asrock z68 Professional Gen 3 Fatal1ty motherboard. When I first hooked everything up (keep in mind this was 2 years ago) I ran into a PCIe problem with my Nvidia gtx 550 ti. I could only get signal from my onboard graphics card and when I would go to the device manager it wouldn't even pick up my GPU. However, I had a 600w PSU and the GPU fan would run (definitely had power coming to it). I decided to contact Asrock and they RMA'd the motherboard and sent it back to me saying everything worked properly as it should. I went back in, bought a whole new HD and did a clean install and the problem STILL existed. I then decided to check the video card, so I hooked it up to my old system and without ANY issues it worked flawlessly. After about 2 weeks of searching forums and trying to update my BIOS, change CMOS, Disable onboard video and everything else I some how managed to get my computer to read my GPU. Well, last week I bought a nvida GTX 780, Corsair 850w PSU, and a brand new hard drive. I hooked everything up, installed windows and I am back at the same exact problem! My gtx 780 isn't getting read, however the fans are running and all wires and connections are properly connected. I decided to get out my gtx 550 ti (that I literally had in my computer for 2 years until I bought the gtx 780 2 days ago) and here I am with the SAME exact problem. It wont read my GTX 550ti now..I tried the card on a different system (both cards) and they work. So the GPU's aren't defective. Now, I can't get the GTX 550ti to come up under the device manager but I am able to get signal from it, I have a mini hdmi cable plugged in and disconnected the analog connection to the onboard video card. So I know my PCIe slots (I have tried all 3) aren't bad and I know my GPU's aren't bad so I know it's driver related. I am very desperate if someone could help me out here.

uninstall and reinstall the drivers for the graphic card also go into bios and make sure that you set video output to pci slot.

I can't install any drivers for GPU because it doesn't recognize a specific GPU. It just says "standard vga" under video devices in the device manager. And the BIOS is set to PCIE as "Primary Video"

I know this may be a dumb question, but PCI slot or PCIe slot as primary graphics adapter in bios? I have changed mine to PCIe as primary and it's been that way the whole time. Also updated my BIOS to 2.20 (newest version). I know for fact it's driver related. Somehow this MOBO pcie driver isn't installed. Yet their website is a little vague as to what is exactly the driver in regards to PCIe

Okay, I inserted my gtx 550 TI and this time it recognized that card. I took the card out and put in the 780 but still doesn't recognize it at all. I decided to try my 780 in my lesser rig (has a 600w psu) and whalla, gtx 780 booted up just fine! However, this older mobo doesn't have onboard video so i am utterly convinced somehow some way my current mobo is overriding my 780 GPU. Doesn't make sense since it will use the 550 but the fact that my 780 is in fact not broken, it's not the PSU, it must be something with my drivers. I hope someone could help me out here
