I have had this problem for a couple of years now. I’ve tried every suggestion I’ve found online, including a full teardown and replacement of the thermal pads/paste. The interior of the console was pristine, with the only thing unusual being the original thermal paste on the CPU seemed to have melted and spread onto the board on all four sides. I carefully cleaned it off with isopropyl alcohol and replaced it. The problem only occurs in certain games and it doesn’t appear to be heat related. I’ve measured the heat coming out the top of the console, and it can happen while running relatively cool, and not happen at all with games that make the console run hot. Some of the most demanding games run fine, while just about every Bethesda game crashes, among others.
My important question for those who also have been having this problem is: what is your build date? Mine is 20-SEP-2021. I’ve read from others on reddit that many of us have consoles made during the COVID shortages of 2021. I’ve also read that Microsoft was using some non-standard components at that time in order to get consoles produced. I’m suspecting there may be a defect in one of those components, but I have no idea which. I’m hoping someone with expertise and a large following could look into this, although I have little faith that the people who make the content actually read these forums. Perhaps if enough people here have the same problem, it could get someone’s attention.
