Gigabyte R7 260x not working in PC

post #1 of 4
Thread Starter 
Hey guys,

I recently bought a Gigabyte R7 260x card.

I posted the following question directly to Gigabyte and it's pending at the moment, but I'd like to see if anybody knows what the problem is:

"When the card is in my computer, the computer won't beep or boot up and no video is shown on the screen (no signal to the monitor).
All fans on the computer spin including the graphics card, but the computer never seems to boot.
I do have the 6pin plugged into the card and it is seated firmly in the PCIe port. (I tried both the 6pin connection from the PSU itself as well as the 4pin to 6 pin adapter that came with the card)

As soon as I remove the card from my PC, onboard works and the PC beeps to indicate that it has booted. This does the same for a number of different cards that I have tried. In other words, the computer refuses to boot with the card installed, under no circumstances. I tried the card in multiple different computers and it works in all of the others but not with this computer. I also returned it to the dealer and they tested it and it seemed to work in all other computers except mine. The facts are, that any other GPU works in my PC seamlessly which should indicate that my PC is not broken in any way.

As soon as the card is installed, my computer refuses to boot and thus no video is shown. Could it be that my motherboard is incompatible or needs to have a BIOS update or that the PSU is not supplying enough power to the card? I have a Gigabyte ODIN 585W PSU and it works with any other card as well."


Product Name: GV-R726XWF2-2GD (2.0)
Operating System: Win 7 64-bit
Motherboard:
Brand: Foxconn
Model: H61MX V2.0
CPU: Core i7 2600
RAM: 4GB Transcend

Any help would be appreciated!

Using the onboard video in BIOS, have you selected "PCIE" as the preferred video device, saved, powered off, and then installed the card?

I have done that as well. Although, I can't set it to PCIE as default when the card is installed as I can't use onboard when it's installed (which I assume is what you meant)

Otherwise yes, I've set PCIE as preferred and reinstalled the card. No difference

Bump.

Still haven't got any reply back from Gigabyte yet.
