I've built many computers... having an issue with these two.
I am using the ASUS H81M-E MB.
I bought two of everything... building two computers.
I put one completely together and booted... nothing happens... never get to BIOS.
So, the second one I just attached the PS and front panel cables to the MB along with the i5-4590 CPU and video cable and same thing... CPU fan spins but that is the only sign of life.
The little speak that is attached to the MB doesn't beep at all.
