Hi Abobiumus /,
Welcome to Microsoft Q&A forum. I'm happy to help.
I'm really sorry to hear that your computer keeps crashing so often, it must be incredibly frustrating.
Thank you for sharing such a detailed description and thoughtful troubleshooting steps. It's clear you're an experienced user with solid hardware knowledge and handled the issue with care and patience.
Unfortunately, based on everything you've shared, it seems likely that your GPU is failing. The best solution may be to send it for RMA, take it to a repair shop, or replace it.
I know this situation feels discouraging, but your clear analysis has really helped us understand what's wrong.
