Hi,
I just assembled my pc, here the list of components:

CPU: Intel® Core™ i5-6500 Processor (link)
UPS: Be Quiet System Power 8 500W (link)
RAM: HyperX Fury HX421C14FB2/8 DDR4 8 GB (link)
MOBO: Gigabyte GA-H170-HD3 (link)
SSD: SanDisk Plus 120 GB (link)

After assembling everything: CPU, Cooler, PSU cables, case cables, etc, the PC does not start, but starts an infinite loop where for 10 seconds the mobo led and fans are lit and then restarts without giving any signal Monitors or system speaker.
I've tried everything, I followed all the advice of this post, I tried disconnecting all the cables one at a time, removing the CPU RAM, removing the mobo from the case to avoid shortcuts but nothing to do.
Can someone help me????
