I dont know whats wrong these are my specs: Gigabyte Z77 Asus Xonar 5.1 Seasonic Platinum 860 watt power supply Corsair Vengeance 16Gb 4 x 4Gb Intel I5 3570k ivy bridge 3.4Ghz (3.8Ghz with turbo boost) EVGA GTX 670 FTW 2Gb vram Seagate Barracuda 500Gb Hdd Lite-on Bd Drive Antec 1200 At first I forgot to plug in the 12v cpu power, but I fixed that. This morning I noticed I put the power buttons cable into the wrong spot because I was following the cases color coding instead of the motherboards. But now I have no idea whats wrong. I have one idea, the screws I used to screw the motherboard in are really long and they stick out of the motherboard. Could that be the problem? Can someone help me I REALLY want to use this pc. I have been waiting for 5 years.
