NEW Custom PC Turns on and off repeatedly

[iLiekPotatos]

I just built my PC and after a few days using it it randomly stopped and I had to turn it off by the power button, now the PC won't turn on, my motherboard has this LED indicating CPU, RAM and VGA, so the motherboard checks if everything is working fine after booting up the system and she goes like this when I turn it on:

CPU LED
RAM LED
CPU LED and shuts down, then it automatically turns on again and it does the same thing over and over again

Here are my specs

It thought it was my CPU Cooler, but no, I called Corsair and they gave a few tips, after a couple days, I just decided to turn my PC and she turned on twice! It worked twice perfectly! I checked my temps and everything was working fine, on idle she goes between 20 and 26 Celsius and on load the highest it has reached is 40 Celsius, when I saw everything was working fine I decided to reset it, and when turning on the problem came up AGAIN, I took everything out, the HDMI, Mouse and Keyboard, and guess what? All of sudden she turned on again perfectly, I re-connected everything and decided to reset it again and she came up with the same problem, turning on CPU LED flashes, the goes with the RAM, then goes CPU again and it shuts down, after that it keeps doing the same process over and over again. I checked all the plugs and everything was plugged fine! So now I believe the problem it's the motherboard itself, I don't know if I call MSI to replace it since I have my warranty, or I don't know if you guys can help me solve this problem. By the way, my RAM was running at @3200MHz and I will add a graphics card to it soon but I need to solve this problem first, I would honestly appreciate the help, thanks everybody.

It seems like you're having a grounding issue. Have you tried breadboarding your system and seeing if the issue is apparent? In hindsight, it also looks like your board is attempting to run an overclock due tot eh X.M.P profile but is failing at it, do not though that you shouldn't be overclocking while on your iGPU as this adds undue stress to the IMC. The stock 2133MHz should cut it very nicely.

On grounds that the system is unstable, you may be able to initiate an RMA for the board but if the issue is persistent then the above is what you need to retry.
