ASrock Z77 Extreme 6 Not Detecting GeForce GTX 680.

[Hammerlock]

I feel like this seems to be a repeat issue by ASrock. I have found similar threads with the same issue.

I have a ASrock Z77 Extreme 6 Motherboard, i7-3770K LGA 1155 processor, 16 GB of Corsair DDR 3 RAM, and a GeForce GTX 680.

I ran into very similar problems.

I updated the BIOS to 1.9. I changed out for an older video card (GeForce GTX 550 Ti) in case the card was bad. I worked through every permutation that I could, but it was not until I went into the BIOS and changed the PCIE link speed to Gen 1 that I was able to Post and Boot Up Windows without using the on-board DVI-D Port.

Any assistance or updates that ASrock could provide would be great, because the issue seems to firmly lie with their product and its configuration.

I had exactly the same problem. I uninstalled card driver.Re-installed. When the computer asks for reboot pause at BIOS. Shift the connection from onboard to 680 GTX. The screen will go blank.
Restart.
