Try reposting this in the 'Q&A' forum. The 'Discussion' forum is for matters of general discussion, not specific problems in search of a solution. The 'Water Cooler' is for non-technical discussions. You can submit a question to 'Q&A' here:

There are TR members who specifically seek out problems in need of a solution. Although there is some overlap between the forums, you'll find more of those members in 'Q&A' than in 'Discussions' or 'Water Cooler'.
Be sure to use the voting buttons to provide your feedback. Voting a '+' does not necessarily mean that a given response contained the complete solution to your problem, but that it served to guide you toward it. This is intended to serve as an aid to those who may in the future have a problem similar to yours. If they have a ready source of reference available, perhaps won't need to repeat questions previously asked and answered. If a post did contain the solution to your problem, you can also close the question by marking the helpful post as "The Answer". .
[b]Though in the mean time[/b] check to make sure that the Video Card is actually fully inserted into the Socket on the M'Board and make sure that it's actually in the x 16 PCI E socket apparently these seem to be more than one PCIE socket on this M'Board.
Some cases hold the Plug In Cards slightly out of the socket and you need to adjust the Back Bracket and M'Board height from the base of the case.
Also if the Video Card had a Power Socket make sure that you plug the Power Supply lead to the Power Socket. ;)
