Hello,
Thanks for reaching out here in the Microsoft Answers Community.
Based on the dump files, it seems that the issue is caused by unreliable memory. If you have set up other overclocking or undervoltage in the system (including XMP), please revert them. You can also try resetting BIOS settings to their default values, and see whether the issue persists.
Disclaimer: Microsoft provides no assurances and/or warranties, implied or otherwise, and is not responsible for the information you receive from the third-party linked sites or any support related to technology.
If you are going to modify BIOS Settings, please back up all your personal files first to ensure you do not lose data.
If the issue persists, since you have mentioned that the issue persists after performing an in-place upgrade, I recommend backing up all your personal data to offline media (like USB sticks, external hard drives, and memory cards), and perform a clean reinstallation, which will wipes all the data and starts from scratch. If that also does not help, we are unable to perform further troubleshooting without access to the hardware, so please contact your local repair shop for a hardware check if that is the case.
To do so, please prepare a USB stick that is at least 8 GB in size (do not use the one with your backups, since it will be erased), then download and run the Windows 11 Media Creation Tool on another computer. Follow the instructions, and when selecting the media type, please select "USB stick", and then select the drive letter the USB stick is in.
After creating the installation media, please plug it into your computer, and boot from it in UEFI mode. The exact procedure differs among motherboard manufacturers, so please refer to the user manual for details.
After booting, please select "Install now". Follow the instructions, and when selecting the installation type, select "Custom: Install Windows only". On the next installation screen, please delete all the partitions (including EFI, reserved, and recovery ones) in your system disk. Select the unallocated space and select "Next". The installer will partition your system disk automatically.
Please refer to the "Clean install of Windows 11 using installation media" section of this support article for further details.
Disclaimer: At this point, we have exhausted all troubleshooting and I recommend that we try to perform a clean install to get your computer back into a working condition. Please ensure that you backup any important data, including Documents, Pictures, Videos, and more.
Thanks for your patience and understanding.
