No signal from GPU - Mobo at fault?

I'm running a Radeon HD 7750 on a Dell B75 motherboard, from an Inspiron 660s.

The crappy motherboard is the only thing I have left to upgrade on my 660s, everything else has been upgraded from stock. CPU, PSU, RAM, you name it. I feel like after a while of running a 7750 and a 3570k this cheap ass mobo might finally be crapping out, whether it be the PCIe slot, or something to do with power phases.

I have been running this card for months, now all of a sudden if I hook my graphics card up to my monitor, I get no signal at the POST / BIOS screen, and everywhere else. The card heats up, and the fan spins, so it's getting power and etc.

With my monitor hooked up to my on board video, (and the GPU in the PCIe slot) If I boot into windows with the Catalyst drivers installed, then windows freezes at a black screen. If I boot into windows with the drivers uninstalled, then I can boot to the desktop. When I go to device manager, Windows reports code 10 on the GPU.

GPU-Z can still detect some info about the card, and when I install the catalyst drivers it successfully detects the card and proceeds with installation, So I don't see how the card could be at fault.

I don't have another motherboard to test the card on, so what do you guys think is the problem: The card or the Mobo?

That was my initial thought, however my bios doesn't support any useful toggles like that. :pfff:
