HI. i just got my graphics card today. I've been waiting for this last componnent for awhile. i have had everything else and this is the last piece to let me know that my comp will run. I plug it in hooked up the pci express cables as well. when i turned it on from my powersupply, i didnt get a green light that i usually got. before my fans were spinning and everything seemed to be running but as soon as i put in the GPU, it doesnt even start. Can u tell me what's wrong and where the problem lies from thiss? i need to know asap! thanks

You need to list the full system specs. I doubt anyone will stab in the dark with a guess without knowing what hardware they're working with.

Do you have both 6-pin pci-e power connectors plugged into the GPU? Is the 4-pin CPU power connector plugged into the motherboard in addition to the 24-pin motherboard power connector?

Your GPU will not work correctly without both 6-pin connectors plugged in.

Can you verify that the wiring is the same for both 6-pin PCIe power connectors? Your symptoms appear like a direct short-circuit of the power supply.
