Hi! Im from Poland, and i have these same problem, i bought new parts, went to home and start build.
My configuration:
Motherbord x79-up4
CPU 4930k 3,40Ghz
GPU GTX 760 Gigabyte Windforce 2GB
Cooler corsair h100i + 2quiet edition corsair fans
SSD Kingston hyperx 120gb
Power supply Corsair HX650
DDR VenegancePro Series 1866Mhz 16GB
Case Carbide600T
I setup all parts together and problem was the same like you, computer start and stop, all the time.
I connected H100i for short to my second old computer to sata supply, and to cpufan connection on motherboard and its doesnt work, and i think that could be a problem. Does h100i should light led on waterblock ? I think it does, so i decied to give him on warranty,also motherboard for sure goes to warranty...
What do You think so? What colud be a problem ? Waiting for Your help, and replay.
p.s sorry for my bad english
