I built my first custom built pc today and everything went smooth and find except for the graphics card. When I turn on my computer the VGA_LED flashes red and I hear a short beep and nothing on my screen. If I plug my hdmi into my motherboard with its onboard graphics it does the same thing but shows the asus sign and fully boots but with my onboard graphics. I really want to use my new graphics card? HELP?

GPU: Asus GeForce GTX 660 2GB Video Card
CPU: Intel Core i7-3770K 3.5GHz Quad-Core Processor
Motherboard: Asus P8Z77-V PRO ATX LGA1155 Motherboard

First make sure you have connected the 12v Pci-e power connectors from the Psu to the top or side edge of the Gtx 660 graphics card.

Once done you will need to go into the bios of your motherboard.
In the bios you will have a section to do with the on board graphics of the motherboard.

You may need to turn the on board Intel graphics solution off if you can.
If not there is an option to change what graphics adapter is used as the primary device.

Change to Pci-e. save the settings/ new changes in the bios.
Restart the system plug the vga cable into the 660 card an it should work.

I've tried changing to PCIE and then I save and reset and it saves my changes and resets my system but when it resets my system it changes it back to auto instead of PCIE??

Make sure the GPU is fully seated in the PCIe slot and the power connectors to it are secure to the PSU (if it's a modular PSU check both sides of the cable). If that does not help, check the CPU socket for any bent pins. Try the other PCIe slot also. If that does not help either, update to the latest UEFI on the ASUS support page and try again.
