Your story suggests the problem is in the video card. Either it still has a bad connection in the PCI slot (try removing and re-installing a couple of times), or it has a permanent hardware fault. Can you borrow another PCI video card and try it instead, to verify that the machine itself works OK?
I would suggest trying the video card in another PCI slot, but I'm not sure you have another one. The mobo manual says there is only one PCIe x16 slot, but maybe you are using a different one.
thanks man tried another gpu and it worked turns out that the other one was dead
