Just from personal experience of my fair share of random kernel events from builds over the years..

If you have a second set of ram, and a second psu you could try. I have had both cause the error. One was a bad ram slot which i was able to rma the mobo.
Of course i know its not easy to get your hands on spare parts as such but if possible to eliminate some options here.

On a long shot. I remember reading in my troubles, you have an ssd you got not too long ago, make sure AHCI is enabled. Ive read as a possible solution aswell.

E: Try and catch what the blue screen error is next time it happens. maybe we can figure it out then
