Your issue appears to be a video card problem or driver. If the other two video cards worked OK then I would contact HP Support and ask for a replacement video card. Go for the 7950.
The problem may be related to PCI-E version 3.
HP's support number is 800-474-6836 or 800-HPINVENT or online here.
I don't see why DVI should be an issue unless the cable or monitor are faulty.

Do you have Windows 7 sp1 installed?
Back on your first posted image from GPU-Z I noticed that OpenCL is not present. You might try removing the AMD Catalyst Suite and then reinstall it.
Review this AMD article for the 7700 series video cards.

I have Win 7 SP 1 installed. Also, the DVI adapter is what HP gave me when the computer arrived. I don't think it's bad.
I'll completely reinstall the driver and see if that helps. Can you explain PCI-e v. 3 to me? Is that to do with the GPU connector? I know what PCI-e is but am curious about the v.3 part.
The monitor I received was from HP with the same order. I tried another monitor to check, but there was not a difference.
If all of this fails I will give support a call. Do I need to mention your name or our conversation? What's the process? I think I will go with 7950. Do you have any info on it?

PCI-E = Peripheral Component Interconnect Express. Electrically there is no difference between versions 1, 2 and 3. The differences between versions is the number of lanes that can send bi-directional data and the transfer rate. PCI-E can also be 1x, 4x, 8x, or 16x depending on the number of pins activated and the size of the slot. Review thisarticle.
Most motherboards will split up the bus bandwidth to the different PCI slots depending on what is plugged into the slots. While one PCI-E x16 can run 16 lanes, adding a second PCI-E x16 card (video) will result in both slots running at 8 lanes. Some motherboards with multiple PCI-E x16 slots with two using 8 lanes each might even disable a third PCI-E x16 slot. ThisIntel article depicts the bandwidth sharing for the Z77 chip.
I wouldn't use a video adapter until you can resolve the issue.
The HP AMD HD 7950 will obviously fit in your PC since its an option. I can't say the same for the retail counterparts as the ones that I have looked at are 10.83" in length.
Sapphire sells three differnet models of the AMD HD 7950.

Can you recommend a 7950 that will fit onto my mobo and in my case? Would HP replace with that or rather retail wouldn't be compatible?
So what could be wrong with PCI-e v.3 in my computer?

I am now fully convinced that there is indeed something wrong with the driver or the GPU. When I went to install the driver update you gave me, I received an error that stated no driver was detected can't continue with installation. I clicked through message to see what happened, and hydra vision came up and asked me to revert or continue. I hit continue. I can try to replicate this msg to post here, but I can't even install it now. I'll give it one more shot.
By the way, during installation it kicked my computer back to the BIOS (?) Boot screen to run diagnostics.
