Hello Jane,
I tried updating the BIOS. It wasn’t like the instructions - as soon as I selected the USB from the boot list, it performed the flashing, GTi204 was on the screen. It was successful, so I rebooted. The BIOS still displays GTi203 version, but since my windows sign-in PIN and fingerprint got removed, I assume it must’ve done something.
Now, the freezes still happen, and more often - less than 10 minutes in game, it will freeze. Also, after freezing, the post-freezing issues (USB, fingerprint sensor not working until another restart) are always there, instead of half the time, like it was before.
Yesterday, after I removed, tested, then put the MiniPC back on the dock, I also reseated the GPU - and had only one freeze in a full day, which was an improvement. Now, it happens more often, and the machine is unusable for anything requiring GPU load (gaming, LLMs, rendering, image generation).
