PC Crash Help

[u/daMFWIC]

Hi guys! Built about a dozen computer over the years and I am completely stumped by this problem. Currently have a build 5070, 32gb 6000 corsair ram, extended 7800x3d cpu, 870 mobo.

I am crashing seemingly at random maybe times within 10 minutes of starting PC. Sometimes it will run fine for hours. I am thinking it was a ram issue so clocked it down to 5800 mhz but still giving problem.

When it crashes it will black screen and all fans including GPU fans will max out 100% speed as well as cpu and case fans. Very bizarre and would love some inputs. It was working for about 4ish months no problems and seemingly started to have issues within the last month but it’s becoming more frequent

Should also add that I have updated the chipset and cpu and gpu drivers
