After upgrading from an i7-4790K to an i7-12700KF, I replaced the motherboard, CPU, and RAM but continued using my existing Windows 11 installation without reinstalling. The system booted normally and activated without any issues. However, when I try to install Windows updates, the update reaches about 30%, the computer restarts, and I get a PAGE_FAULT_IN_NONPAGED_AREA (0x50) blue screen. Windows then restarts again and rolls back the update. I have already tried common Command Prompt repairs such as DISM RestoreHealth, but they did not solve the problem. Is there a way to troubleshoot or fix this without reinstalling Windows?

If the crash is happening during the update, a dump file could provide more detail about the driver or memory address involved. Check C:WindowsMinidump for .dmp files. If the folder is empty, enable small memory dumps and check again after the next crash. Since the hardware platform changed significantly while keeping the old installation, incompatible drivers are also worth considering.
That stop code can be caused by faulty or unstable memory. Even if a previous RAM test passed, try running the system with only one memory stick installed, then swap sticks and motherboard slots to identify whether one module or slot is causing the crash. Also make sure any memory overclock or XMP profile is disabled while testing.
I’ll test each stick individually. I did run a memory test before and it reported no errors, but I’ll try it again with the modules separated.

I checked the Minidump folder and there aren’t any files there.
