Graphics card preventing computer from POSTing, any ideas?

Ok, so I have a XFX geforce gtx 260 Black Edition, while its in the pc it basically won't allow my computer to boot, absolutely nothing comes up on the screen, most of the time, no motherboard tones or anything, once in a while you might get 10 motherboard tones, which should be the cmos right?.But, the computer will boot just fine with a different graphics card (Geforce GT 430) installed, I've tried various things, such as making sure the aux power connectors are properly connected, all the motherboard connections etc, still the PC refuses to boot with this video card installed. The video card is free off dust (as I've cleaned it recently, so it isn't over heating. When it was working (a few days ago) it used to stay at around 70 degrees c while it was running a game. I'm beginning to assume the video card is just dead, but this seems like a very odd fault, so if you have any ideas at all what could be causing this, give me advice, thanks in advance

Update:

Yeah the psu is a 750 watt coolermaster, so it's definitely getting enough juice.

Update 2:

and yeah, it takes 2 6 pin pcie connectors.

    Beginning to think that the video card is just dead is pretty much the correct conclusion.

    My video card died and would prevent a successful POST. Replaced the card and all was well again. Can you perhaps stick the card in a different machine to see if it posts? If it doesn't, well there's your problem.

    Video cards do die. It's not uncommon. But XFX have great warranties. Perhaps you could get a replacement for free.

    Do you have a big enough top quality power supply and the correct power connectors (PCI-e 6pin or 8pin) for that graphics card? It looks like it does not get enough juice to power on...

    It could also be dead, like someone suggested here. Graphics cards are very sensitive to static and can easily be damaged by improper handling.

    Also your power supply might be busted or just worn out.

    SOLUTION:

    1. Try that card in a different computer, see if it works.

    2. Replace your power supply with an 80 plus certified PSU, from a reliable brand name such as Thermaltake, Enermax, Cooler Master, Antech, OCZ, or Corsair.
