Hello,
Just did an upgrade to a pc... new mobo (asrock z77 extreme4), new ram, new video card... same old hdd and psu. I eventually got everything working and was trying to get it to hibernate (win7)... it kept waking itself up. I found that the ethernet was set to wake the pc when it received a signal. I disabled that feature using windows control panel. The pc would hibernate, but when I went to wake it, it only powered on for .5 seconds, then off again... the repeated. On and off. On and off. The case fans and leds that I have turned on, then immediately turn off. Now, that is the only thing that the pc will do. I can't get it to post, can't get into windows. Could this be a power supply issue, or is the mobo bad?
