Hello, I recently put together a new PC with the following products:

FORTRON Green-PS-600 80Plus 600W PC Power Supply

Gigabyte H110M-S2H Motherboard (Socket 1151, H110 Express, DDR4, S-ATA 600, Micro ATX)

Intel BX80662I36100 Intel Core i3 6100 Skylake Dual-Core 3.7 GHz Processor


PowerColor AMD Radeon HD7870

CORSAIR Vengeance LPX Black DDR4 PC Memory - 2 x 4 GB DIMM RAM

All the pin connectors are in securely including the front I/O buttons.

The System turns on. CPU fan & Graphics card fans both run ok. HDD also runs ok.

Then after a few seconds a small motor sounds begins (as if the computer wants to begin booting) and then it cuts out. Stays off for a couple of seconds and then restarts and repeats the process.

Not to sure what the problem is. Wether the power supply is too little/too much or the problem lies somewhere else.

I have done the general POSTing setup which guides you through certain sets to ensure the PC is ok but no luck. Any advice?
