After upgrading from an i7-4790K to an i7-12700KF, I replaced the motherboard, CPU, and RAM but kept using my existing Windows installation and system drive. Windows 11 still booted normally and remained activated, but it would not install newer updates until now. During the update process, the computer restarts at around 30% and crashes with the stop code PAGE_FAULT_IN_NONPAGED_AREA (0x50). It then 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 diagnose or fix this without performing a clean Windows reinstall?

The most likely starting point is the new RAM, even if an earlier test passed. Test each stick separately, using the motherboard's recommended slot, and try the update with only one module installed. Also consider running a longer memory test and returning any XMP or manual memory overclock settings to default. A marginal module or unstable memory settings can trigger this stop code during an update.
Check whether Windows created any crash dumps in C:WindowsMinidump. A dump file can identify the driver or component that caused the PAGE_FAULT_IN_NONPAGED_AREA error. If the folder is empty, make sure small memory dumps are enabled and check again after reproducing the crash.
I checked that folder, but there were no dump files there.
I’ll test the sticks one at a time. I did run a memory test before and it reported no errors, but I’ll check again.
