System shutdown and now stuck in a reboot loop

Hello,

So I've read a lot of other post with the similar problem but can't seem to fix the issue. I built a computer for my friend and he said he was playing on it one day for about an 1 and half then suddenly it shut off out of no where and now when I try to reboot it there is no video picture but all the fans run for a sec then looks like it shuts off then they run again like a loop. I thought it may be something with the GPU card but it is inserted into the motherboard good and it will power on with the fans and does the loop as well. I also tried inserting the HDMI cord into the motherboard directly to see if that would fix it and nothing. I'm kinda guessing it could be the motherboard or maybe the CPU but can't figure it out. Any ideas or help would be appreciated, thanks.

Specs:
Nvidia GTX 1060
Gigabyte LGA1151 Intel z170 mini-itx ddr4 motherboard
Intel Core i5 6600K 3.50 GHz Quad Core Skylake Desktop Processor, Socket LGA 1151
Cooler Master Hyper RR-212E-20PK-R2 LED CPU Cooler with PWM Fan, Four Direct Contact Heat Pipes
Samsung 850 EVO 500GB 2.5-Inch SATA III Internal SSD
G.SKILL Ripjaws 4 Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM 2400 (PC4 19200) Memory Kit F4-2400C15D-16GRR

I took it apart and looked at everything and nothing looks like its in bad shape.

And make sure unplug the power cord from wall outlet, remove all the RAM, the samsung SSD ( assumed it is the boot drive), still use onboard iGPU, clear the CMOS again, then plug the power cord back to boot the PC.

If you still get the same, the pc does not boot. Then most likely the MB has problem.
