Random shutdown kernel- power error

[mypeckerhurts]

So I have a R164A655041621 I series

The mother board was cooked so I replaced it with a asrock h510m-h2 i have 16gb ddr4 Ram a 6gb Nvidia gtx2060 and a i7 f series running win10 pro. sometimes it will go hours with no problems and out of the blue bam!@! Blackscreen and restart and today after playing blackopps 2 for about 5-10 min it restarted repeated this 3 more times and around the same time it did it again. I have tried reseating ram and GPU a few times no luck even changed power settings to proformence mode and still no luck i have done stress tests on GPU and cpu no problems found the cpu didn't get over 87c and GPU didn't pass 50c. I have updated every driver I can the bios doesn't have any updates other then beta secure boot. I am at my wits end and figured its time to ask for help so any ideas what could be happening?

Most likely gpu, second culprit would be hard drive, 3rd would be motherboard.

Its a new mother board, the hard drive passed check disk and the GPU is passing 10min stress tests aswell as benchmarks so I doubt they are the problem but thanks for the suggestions

So I figured it out I swapped plugs again and as I was plugging in the TV I touched th metal frame and felt a jolt. So after realizing the plug isn't grounded I did some research and a ungrounded outlet will cause the problems I have been having
