ASRock Extreme3 Gen3 not detecting video card

[Sopharus]

I've just finished assembling a new build here (details below), but after trying my video card in both PCIe2 and PCIe4, I cannot get this mobo to detect my video card. I did get it to boot and install Windows via onboard video, but device manager doesn't appear to be recognizing my video card at all. I've done a bit of searching on the forums here and elsewhere, and it sounds like there were a few others having this problem. Unfortunately, I don't have another machine to try this video card in. I was planning on RMAing it but I guess I wanted to double check I'm not doing anything dumb first.

Steps I've tried:

• Updating bios to current version
• Ensuring bios should default to PCIexpress
• Resetting CMOS (both using button on back, and mobo jumper)
• Trying card on both PCIe ports

Build:

• ASRock Z68 Extreme3 Gen3
• XFX Radeon 6970 2GB
• OCZ 700W PSU
• Intel Core i7 2600K
• 8GB RAM GSkill RipJaws
• 120GB SanDisk SSD

If anyone has any suggestions, I would definitely welcome them. Thanks!

Re: ASRock Extreme3 Gen3 not detecting video card

I bought my new computer from Cyberpowerpc.com and I have the same issue.

ASRock Z68 Extreme4 Gen3
HIS radeon 6870
Thermaltake 850W PSU
Intel Core i5-2600K
16 GB RAM kingston
120 GB OCZ SSD

My video was detected for 1.5 days, then not anymore. Then later it was detected again for 3-4 days then notanymore again.
I uninstalled and installed again Windows 7 or Windows XP about 5-6 times.
I updated all the drivers and the BIOS from ASRock.com, and nothing.
I bought a new video card Sapphire Radeon HD6790 to put it in the second PCIe port, nothing.
Fan from both video cards are spinning.

So I have 2 video cards that are not detected ! Not really fun to play !
Is there a trouble with the PCIe ports?
