Cant get motherboard to power up tested multiple power supplies, reseated the ram and cpu. The only time the system even comes to life is when I reset cmos the cpu fan spins up for 1-2secs and shuts back down!
Specs:
PSU: Thermaltake tr2 700wat
CPU: i7 3770k
Ram: Corsair Vengeance ddr3 1600mhz 16gb 8x2 1.5v
VGA:TBD
HDD: 2 Seagate 250gb sata drives

Could be a defective MB. It happens. But take the MB out of the case and breadboard it. Set it on an insulated surface with just the CPU/cooler, RAM, keyboard, PSU, monitor attached to on-board video. Nothing else. Short the two pins the pwr sw. would connect to to start. See if you can boot to BIOS. If the same problem occurs, I would RMA the board.

The PSU works on my older system with 4pin 12v and runs. I don't have an 8 pin system to try the PSU on I have removed the CPU and re applied fresh Artic Silver 5 every time I re seat the CPU.

Thanks ill try that when I get home. I can't RMA with Newegg because I already submitted my rebate they offered on that board so they said it voids there 30 day warranty policy, so lesson learned test before you submit your rebate. I submitted a RMA claim with Gigabyte just waiting on approval.
