If you can live without it, I recommend you rma the motherboard back to the vender. It may take 2-4 weeks to get a new one, as the old one will have to be tested. You might be wasting your money on a new power supply. I use a 235 watt sparkle, and have my 1.2 running at 1.33 with no problems. What brand power supply do you use? Are you overclocking?
