Computer reboots with dxgkrnl.sys as the culprit

[Abom1331 0]

Hello there.

Since last day (15/10), my computer started rebooting out of nowhere, while playing games. Issue started while playing a recently released game, Battlefield 6 (which requires Secure Boot).

Game stopped responding, just a black screen, and computer auto reboot. Wiped GPU drivers via both AMD Cleanup Utility, reinstalled new ones, same. Black screen and dxgkrnl.sys issue.

Cleaned again via DDU, reinstalled drivers, dx12, same. Reinstalled entire Windows 11 from the start, as fresh installation,

Only software at the moment i have installed: Open Shell, Steam, Ubisoft Launcher, WizTree, Realtek+Sonic Audio Suite, AMD Adrenalin & a download manager.

Again, after a while, a different game this time (Avatar: Frontiers of Pandora) stopped responding, and computer went into reboot state after a black screen with dxgkrnl.sys as the culprit, as usual.

Even minidumps (and the folder) are not created at all within, (virtual memory set to automatic / both complete or automatic memory dumps not creating anything) and event viewer shows the following message:

"Dump file creation failed due to error during dump creation. BugCheckProgress was: 0x00040049".

So, tried to see if i can solve it by my self, and i see the following:

VIDEO_MINIPORT_BLACK_SCREEN_LIVEDUMP (1b8) <- was 1a8 previously
PROCESS_NAME: dwm.exe
IMAGE_NAME: dxgkrnl.sys

Checked reliability history, and here two (2) images with details:



Also, V2 Log Collector was unable to get crash dumps, since there's no minidumps folder created at all within "C:\Windows". Instead, i found the last two (2) reports inside "C:\Windows\LiveKernelReports", and i attached it here, along with Gather_additional_dump_files log + Tuneup_plus_log (not sure if last ones needed).

Please, if any help. Computer keeps rebooting while gaming, and I don't know what else to do, and/or where to ask for advice(s), and I don't have another Computer for testing purposes, or the financial state to buy again new parts.
Entire computer parts are brand new (expect GPU, bought back at 2023), from a month ago. Thanks in advance for any help.
