I just got my parts yesterday and I put everything together, everything was good until I had begun my first test boot. I plugged the plug into the wall and turned the switch on my psu on. The system immediately began running, all fans spinning, including the cpu and gpu fans when suddenly everything turned off except for the LEDs on the clr CMOS and power/reset buttons built onto my motherboard. I checked every single cord and part and tried it again with the same results. I thought that it would be the memory as I had checked the debug codes which indicated that the memory wasn't installed and the cpu type or speed was wrong. I was looking at another thread on tims where the memory problem was causing the cpu debug code aswell as the memory code.
My setup is as follows:
Psu xfx xxx 750w semi modular edition
Mobo asrock fatal1ty z77 professional lga 1155
Cpu 3750k lga1155
Memory corsair vengeance 8GB (2x4) 1600mhz ddr3
Kingston SSD 120gb
