Previously installed Windows 8.1 Pro on a new build the other day, but now it boots without displaying.

So, as a new builder, I gathered all of my sources to build a fairly decent system with an AMD FX-8350, Gigabyte GA-970A-UD3P, 8 GBs of ADATA XPG V2 RAM, ASUS R9 270X 2GB, 128 GB SanDisk SSD and a 2 TB Seagate HDD. But anyway, I was built the system a few days ago, booted it up, and it was able to POST to be able to install Windows 8.1 Pro. I was able to set up my accounts and install drivers, no problem. Now, two days later, I go to boot and nothing is displayed on the monitor. It appears to be going through a full boot cycle, as my NumLock LED is on, the HDD LED is active, all fans are running (including CPU fan), and the Ethernet Port LEDs are active. Even the power LEDs and fans on the graphics card are running. After trying to boot again, I decide to switch to a different monitor, still using HDMI, and again, nothing. I then tried with DVI on two different monitors, and now I am stuck. What could be causing the problem? I don't think it is a problem with the motherboard, could it be with the graphics card?

  1. It could be but before you go replacing the anything reseat the GPU by removing it and reinserting the GPU making sure that the card is fully in the PCI-E slot. I have seen cases where the GPU is not quite inserted and the back side of the card can get jard up just enough to not make full contact with the slot.

    When I tried that earlier, I happened to notice on the smaller tab of the PCI-E connector that the leftmost pin was somewhat shorter than all of the others, almost like 2/3 of the way of the others. And it didn't look right, could it have something to do with that?
