A bit of an odd one this. I don't seem to be able to get past the motherboard splash screen on one of my PC's. It seems to just hang and I can't enter the BIOS (via F2 or DEL). I've tried clearing the CMOS, made sure everything is connected properly, tried one RAM stick, RAM sticks in alternate slots, on board graphics and a separate card (get display on both), the bare minimum connected (power, HDMI, usb receiver for a keyboard). I'm at a loss as to what maybe causing it. The only thing I haven't tried is a wired usb keyboard as I don't have one. Any ideas?
