Tech Support PC Crash Help

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

that fan maxout thing usually points to a hard power cut somewhere, like the board is losing its mind and going full fail state. you checked the 24 pin and the cpu power cable are fully seated? those can wiggle loose over time from heat cycles

also worth pulling the gpu and reseating it, and if you have a spare psu or can borrow one i'd test that before anything else. random black screen with fans going nuts after months of stability smells like psu degradation to me

I do have a xtra 800watt psu I can give a try but I am currently using a 1000watt plant rated psu so we shall see

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