Windows 11

My PC restarts unexpectedly

The restart time and nearby events help narrow the cause.

TRY THIS FIRST

Check the event at that time

Open Event Viewer → Windows Logs → System. Find Kernel-Power 41 around the restart.

Start with this check

Result: Use what you find to choose the next step.

Still not working?

Use the Kernel-Power 41 entry for the next check. The event alone cannot tell you whether the cause was a driver, power loss or a forced shutdown.

Check the result: Repeat the original task after making one relevant change. If the problem returns, keep the exact message and time.
