Windows 11 Daily Random Crash/Shutdown

My computer is crashing (random shutdown, no restarts or BSOD) several times daily and has been for a month or two. At first it was sporadic, and I thought related to overstraining the system while gaming, but it would also crash during sleep mode almost inevitably. Now it crashes three or four times in the first 10 minutes after startup and then runs almost as normal for the rest of the day. (And by as normal, I mean it still might crash 1-3 times after that. If put into sleep mode or switched off during the day, the pattern repeats.)

The pattern is similar while gaming: the system will crash a few times immediately after starting a game (even on initial load screens) and then work fine for awhile (with intermittent crashes).

When the computer does shut down, the case fans go into high gear as though it had overheated (no indication that it is overheating) and remain running on high speed until I press the on/off button for a manual shutdown.

The system has only been able to create minidump files a handful of times.

After researching on these forums quite a bit, here are some of the things I've tried:

• Windows update
• Upgrade to Windows 11 (the problem started on 10, I upgraded, it continued or worsened)
• Windows check all drivers
• Manually update graphics and sound drivers (the graphics were way out of date but new drivers didn't change anything)
• Change all the various power and sleep mode settings recommended for random Kernel 41 errors for other similar situations

Of the causes I've seen suggested in similar situations, I think I've narrowed it down to:

• a BIOS problem
• a PSU problem

But with random shutdowns and the possibility of destroying my system if a BIOS update is in progress, and the cost of buying a new PSU, I don't really want to try these on my own without seeing if I can get a more concrete diagnosis for the problem. (I don't have access to a spare PSU, or I'd plug that in and see what happens.)

Thanks in advance to anyone who can help!
