GPU Troubleshooting

I built a PC in January with my friends old NVIDIA GT 530 GPU (It's from an old ASUS PC). I wanted to get good parts so I thought I would use that for a few months until I could save up for a new card. Last week I purchased an ASUS GTX 670 1058 edition (they have the standard 915MHz, 1080MHz, and 1137MHz which in now discontinued). I got the card in the mail from Newegg and installed it in my PC, but when I try to boot up I get "no signal" from my monitor. My PC acts as if nothing is wrong. The green LED's on the card light up signaling they are getting power from my Corsair 650 650W PSU, and the fans on the card and case spin up as normal. The debug LED's on my ASUS Maximus V Gene say AO, meaning that the PC has posted and has handed it over to Windows 7 (This is what it says with the old working card too). The old card works in both PCI slots on my motherboard, so the PCI slots are not broken and the 670 also doesn't work in either PCI slot. I have tryed all outputs on the back of the card eccept Displayport and none work. I also uninstalled the old drivers for the 500 series for the old 530 I was using before I plugged in the new card. I have been reading other forums and they all say stuff about PSU's, disabling integrated graphics, and drivers, but I don't know if that applys to me. Did I get a dead card or is there something I can do?

I've seen this issue lately, but I don't think I've ever had it before. The closest I've had was my PC would faill to POST when I installed my GTX 570, but I realized I didn't have one of the 6pin connectors in all the way. I suspect that if the same thing happened to you, your PC would revert to integrated graphics, but I don't have that option since I'm on a p67 chipset. I'd double check power connections.

If you still have the issue, try plugging the monitor directly into the motherboard.

I have removed the card several times and unplugged and plugged the cables in each time. On the ASUS 670, there are two green LED's above the 6 pin power conectors and both are green meaning my card is getting power. I think I might have to disable integrated graphics, but the card might just be dead. I am taking it over to a friends house tomarrow to see for sure but until then I'm just going to mess around with drivers and the BIOS. If it is dead, I would like to tell Newegg soon so I can get a replacement and hopefully that will work.
