Hi, i just finished my pc build. When i press the power button on my case all my fans (including cpu and gpu fans) turn on. All usb 2.0 and 3.0 work too but when i try to plug in my hdmi or vga cable from the display to the motherboard nothing happens. My mobo: gigabyte ga z87 ud3h. Also the debug lights on the motherboard say Ab which means: Wait user command in BIOS setup. My display and cables are fine, i really dont know what to do. PLEASE HELP!!
