Mobo: MSI B350 Tomahawk Artic
CPU: Ryzen 7 1700
Ram: 8gb Hyperx Fury 2400mhz
GPU: R9 270
Power Supply: EVGA 500W
SSD: 250Gb (Also can't tell you brand off top of head)


All parts new except for SSD, and Graphics card. Everything else purchased new for the build.


Now to the problem! I've build dozens of PCs in the past and never have I had so much troubles getting it to work.

First start, all the fans where working, everything was looking good, BUT CPU debug light was on, and no post. A few restarts later and finally BIOS! Great, restarted, put in windows 10 install disk, installed windows, installed necessary drivers, installed steam, PUBG, was running great, better than any other build I have done, but that CPU debut light was still on. Did restarts that night after installing various drivers etc.

The next day, turn on the pc, open up Chome, watch Youtube for maybe 5 minutes and then screen when dark and displayed no input, mouse and keyboard where no longer illuminated. Restart, nothing, all fans kick in and everything looks like it should work, but that CPU debug light is still on. Couple more restarts nothing, I took it all apart and back together, didn't work, one more restart and it worked! Got another night of gaming out of it.

Day 3, same situation, turned it on for 5 minutes and screen goes dark, exact same thing that happened day before. Except this time I can not get it to post no matter what!

Tried:

-Bare Bones test, with and without GPU, moving ram and trying in every slot, and without ram entirely.
-Reset CMOS, both by pulling battery and short pins.
-Tried different power supplies, different Ram sticks.
-Tried different monitors, both with HDMI and VGA
-Took out CPU and re-installed, new thermal paste etc.

The mobo box has Ryzen logos all over it! Gotta be compatible, especially because it's worked a couple of times!

I'm out of ideas, and any input at all would be appreciated!
 
Solution
Try taking the motherboard out of the case and test it setting on the motherboard box. Test it to see if the motherboard was grounding on the case. Try only 1 stick of RAM to see if the motherboard has a bad DIMM slot. Check your CPU for bent or broken pins and if you find none RMA the motherboard.
