Hi there after a while,I have a chance to reinstall fresh OS Monterey and the results are the same after interacting for an undetermined time.the screen freeze and become totally unusable and need to manually turn off,start up normal and after a few minutes same all,I’m not a skillfull on this matter and I don’t have any idea what could it possibly be failing thanks in advance for any advice (have a different backboard the old one replaced because it happe the same,change the cpu tray with a different one and it works fine on its own machine and mine even works well in that machine but no one works well in mine ) the cpu tray is good change the PSU and still does the same so I don’t know what else to do thank you all have a good week!
