    I have seen a lot of other posts about Gigabyte mobo's and the Phase leds green,green,amber and red with no bootup. My pc was running for a few years with the GA-Z68XP-UD3. I did not make any changes, did not move my pc etc. I came home one day and my pc was off then would not boot. When I hit the power on switch the power supply will kick on for a split second and shut off. I tested the power supply and it passed. The power supply is an OCZ 700 Watt. I ordered a new mobo, same one, installed and had the same problem. I have disconnected everything and still can't power on. The only thing I can say is my UPS had a red light on it indicating a problem. I shut off the UPS and turned back on. The red light was gone and only the green light was on. I have plugged in my pc to an outlet instead of the UPS and same thing... Any success stories out there with this problem?

    I just joined the forum today so that is the reason for a lack of specs. My system was running for years and everything was solid. I have tried powering up with everything disconnected exept for the minimum and no luck. My next attempt I will remove the mobo from the case and try power on outside the box. I do have a case speaker but disconnected that for the troubleshooting.
