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?
