Random PC cut outs

[Jihakuz]

Hi all,

 

I've recently started having the problem where when I put my PC under load it will cut out, kind of like an OCP when over clocking. However, I run my PC stock because my motherboard is janky (OC is limited at best, the onboard NIC doesn't work and the BIOS decided to lock up every once in a while).

 

My specs are:

• Ryzen 7 1800X @ stock
• MSI X370 SLI Plus
• MSI Armor 1070
• Corsair Vengeance LPX, rated for 3000 MHz but at 2133 MHz (or somewhere near that number)

Could anyone give me a clue as to where to start looking to fix this problem? I assume I will need to get a new CPU / MoBo
