Help with random PC power cycles

[Phoenix30]

Hi All,

I recently came across an issue with my computer that I can't seem to fix.

Randomly when I'm using my desktop it will do a power cycle that can do one of 2 things: fully restart the PC, or put the computer into a weird limbo state were the fans still spin and my LED's are still on but there is nothing displayed.

When my computer gets put into this weird limbo state pressing the reset button or holding the power button for 10 sec will not work.

Does anyone have any ideas to what the issue could be?

 

PC specs:

Ryzen 5 1600x O.C. to 4.0 GHz (this issue still happens at stock speeds)

Asus PRIME X370-PRO motherboard

Crucial DDR4 Sport  4GB x4 Ram

MSI Titanium GTX 1070 TI
