Question Inconsistently recurring - Critical Errors (Kernel Power 41-(63))

Hi all,

I built a new PC about 6 months ago, and it was running fine for long periods but then started with random BSOD (every time with a different text, but always the same event ID in Event Viewer - Kernel-Power 41 (63).

I recently did a full format and clean Win 10 install, which fixed the problem for a week, but now its back.

I cannot correlate it to any specific activity as it seems to happen at random (sometimes 3 times in an hour, sometimes not for a week).

I have run MemTests, CPU checks etc. but everything seems to be fine.

I am going crazy and am really desperate for help. I have uploaded my latest files in case it is helpful:
Mindump
MEMORY.DMP (as txt)

Let me know if there are any questions or any more information I need to add (sorry my first time posting here)

MANY thanks in advance.
Best

Update your post to include full system hardware specs.

Include PSU: make, model, wattage, age, condition.

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all connectors, cards, RAM, and jumpers are fully and firmly in place.

if it survives a clean install its unlikely to be windows

but always the same event ID in Event Viewer - Kernel-Power 41 (63).
this is a reaction to the restart, not the cause of one. Windows runs a report at every startup and if it finds the previous shutdown was unexpected, it creates that event to say, hey that restart, it wasn't planned.

I will ask someone to look at dumps, see if they show anything

that is an odd error, windows was stuck in a loop

actions are in 1st in last out order, so bottom items were 1st

it repeated those steps 5 times before it requested another page fault location and crashed

page faults are normal action of windows 10, badly named. Any time the CPU finds it doesn't have immediate access to the info it needs, on its caches on chip, it will issue a page fault and request info from ram. Since you have run memtest, it could be a driver error
