key word in windows 11 event viewer: is my device faulty that it reboots randomly?

0x80000000000000 by itself does not identify the cause of the reboot. For random reboots in Windows 11, the useful data is usually the reboot-related Event IDs and any stop code or dump information.

Provide these details first:

1. System Event Viewer entries around the reboot
   • Open Event Viewer.
   • Go to Windows Logs > System.
   • Check for these Event IDs near the restart time:
     • 41 = system rebooted without clean shutdown
     • 6008 = previous shutdown was unexpected
     • 1001 = rebooted from a bugcheck, often includes bugcheck code and dump path
     • 1074 = a normal/user- or process-initiated restart
   • If the pattern is 41 + 6008, that indicates an unexpected reboot.
   • If 1001 is present, it can show whether a bug check occurred and whether a dump was saved.
2. Any stop code shown on screen
   • If a blue/black stop screen appears, note the stop code such as PAGE_FAULT_IN_NONPAGED_AREA or MEMORY_MANAGEMENT and any module name shown.
3. Whether a dump file was created
   • Event ID 1001 can indicate a dump was saved in C:\Windows\MEMORY.DMP.
4. Recent changes before the issue started
   • New hardware
   • Driver installs or updates
   • Application installs
   • Windows updates

A practical troubleshooting path is:

1. Review reboot history in Event Viewer
   • In Event Viewer > Windows Logs > System, filter for Event IDs 13, 41, 1074, 6008, 6009.
   • This helps separate normal restarts from unexpected ones.
   • To check history around when the issue began, also review 12, 13, 19, 41, 1001, 1074, 6008, 6009, 7045.
2. Check whether this is a bug check or a lower-level reset
   • If Event ID 1001 appears with a bugcheck, Windows detected a crash.
   • If there is 41/6008 but no bugcheck details, the restart may still require hardware, driver, firmware, or power investigation.
3. Try the standard Windows 11 recovery steps
   • Remove any newly added hardware.
   • Start in Safe Mode and test there.
   • Open Device Manager from the Start button menu and look for devices with an exclamation mark. Update the driver, or if needed disable/uninstall the affected device.
   • Make sure the drive has about 10% to 15% free space.
   • Install the latest updates from Start > Settings > Windows Update > Check for updates.
   • If the issue continues, use a restore point or another recovery option.
4. Focus on drivers if the reboot started after updates
   • Unexpected reboot history can help show whether a new driver or update was installed shortly before the first failures.

What to provide for useful diagnosis:

• The exact Event IDs around one reboot
• The full text of Event 41, 1001, and 6008 if present
• Any stop code shown on screen
• Whether C:\Windows\MEMORY.DMP exists
• Whether the issue started after a driver, BIOS, app, or Windows update
• Whether the reboot happens during gaming, idle, sleep/wake, or startup
