GTX 480 not displaying after installing new cooler?

post #1 of 6
Thread Starter 
i bought a Zalman zf3000f cooler, and installed. beforehand the GPU worked, but afterwards it just keeps displaying a black screen and i hear POST finishing, even windows starting. just a black display.
the screen is still lit up too, it just isn't displaying anything.
any ideas on what it could be?

You sure the card is plugged back into the PCIe slot all the way? And the external power is connected? Otherwise might be a short somewhere on the card, you might need to take the cooler off and make sure nothing looks messed up.

i made sure for both. my case (NZXT Phantom full tower) makes it tough to fit the card in the PCI slot, but i'll try it again. it's always slightly out, but most of it fits in. i'll try it with an open case and see if it works fully in.

sometimes it helps to remove the pci slot bracket to seat the card in all the way, although that may not be a good idea with a heavy aftermarket heatsink on it like that.

like the person above said, I would double check the new cooler is not shorting something out somewhere. worst case install the ref. cooler again and see if that helps.

Sounds like you have shorted something on the card... just make sure that the slot is clean and that you have plugged the DVi or any cable that you're using into the back of the card... sounds stupid but some people have made this mistake before

I've had issues like that too. sometime the metal bracket with dvi ports on the card does not line up with the case, and the card ends up not being completely in the pcie slot
