Similar story here. 13700KF, no OC, had the machine put together 18 months ago at a respectable shop (Central Computers for those in the bay). I had regular stability issues and blue screens to the point I took it back to the shop after three months - they couldn't find anything wrong. Took it in again at nine months with increasing frustration - nothing. Probably should have taken it again three months ago when I was playing the new Helldivers and that would crash the machine every other time I joined a game, but by that point I was pretty exhausted by the whole thing (and the game had other, unrelated bugs that had me looking elsewhere).
Odds are good I won't be bothering with Intel hardware or recommending it to others for the next decade or more - this has been a flatly terrible experience (and I'll note the irony of finally deciding to spend on a "dream build" and this being the result).
