JimmiAlanXCIX What exact hardware test did you run? It may or may not be reliable and may or may not test everything. I'm not saying you definitely have a hardware issue, only that this would also be useful info.
Since your newer dxdiag did have one crash of a component of the graphics driver, try doing a clean uninstall and reinstall of both drivers, as described here:

Use the drivers Dell provides for your laptop, the Intel UHD/Xe and Nvidia drivers dated November 2025 and February 2026, respectively:

The Nvidia driver doesn't list compatibility with a 3050 ti, but it'll be fine since it supports a 3050.
The proper order of operations is uninstall the Nvidia driver > uninstall the Intel driver > restart > reinstall the Intel driver > restart > reinstall the Nvidia driver > restart, all while your computer is offline.
