The parts I have are gigabyte z77x-d3h, intel i5-3570k, noctua cooler and a 850W trupower supply. These are the only parts plugged in right now and the mobo is sitting on a wooden surface. The computer will turn on for about 10 seconds then shut off. It will then come back on for another few seconds then shut off. It will keep repeating this. I have tried a new power supply, the stock cpu cooler and it all does the same thing. Also the first mother board i had did this exact thing so I switched it out for a new one and its still doing the same thing. The chipset was also swapped for a new one. Any ideas?
