Update the bios to the latest one when you can.I registered just so I could say thank you. The solution worked well for me after my system went to sleep one day and refused to wake up...I even bought a new PSU and tried testing with it and got nothing. There were no lights at all just like the board was getting no power. I cleared the cmos and then pulled the cmos battery for about 15 seconds and sure enough, the system came back on. I will update if I need to keep doing this.
