I just built a new PC with a Gigabyte GA-X58A-UD3R and it worked fine for about two weeks... Then I noticed a ticking sound coming from the motherboard speaker (not a fan, not a hard drive or dvd drive).
After the ticking started the computer would not wake up after it went to sleep, the mobo speaker would just tick away like a clock.
I took the mobo out and bench tested it. The Motherboard Speaker is Ticking when the ATX_12v_2x is connected.... Disconnect it and the ticking goes away.
Any suggestions? Bad motherboard? Bad Power Supply?
