I just finished my first build. The power's on everything is working. At first when I had the Gigabyte GTX 770 4GB installed the CP would short beep once and there would be no display. The fans were running. I took the GPU out and tried again. This time Bios works perfectly, but still the same beep. I Dont understand how to get the Gpu working. As this is the first time working with bios. my motherboard is ASUS Z87-a. my PSU is a corsiar TX 750. I have a total of 5 120mm fans running. I could sure use some pointers. is it because I need to install the GPU drivers? I cant put window in yet because my DVD drive has not been shipped. Hopefully i can get this figured out. I'm really excited to get this working
