So I just bought my H100i v2 and decided to plug it in. Since I was new to computer building it took me a few hours to take off the old CPU fan and put on the water cooler. I got into on but I ran into a few problems. 1) the backplate seems offset on the back of the motherboard so the h100i isn't completely 100% touching the CPU.

2) i couldn't find enough pins to have my CPU fans running and the h100 fans running.

MY MAIN PROBLEM:
My computer doesn't turn on for more than a second, if I'm lucky it'll turn on until i click my Mozilla Firefox. Help.
