Hi Zaineb Ismail,
Since the reboots began before the BIOS and chipset updates and continue afterward, the Event ID 41 entries are mainly confirming that Windows detected an unexpected restart rather than identifying the root cause itself.
To narrow this down, I'd focus on checking for underlying hardware stability issues:
- Open Reliability Monitor (perfmon /rel) and look for any hardware, driver, or application failures that occur at the exact time of a reboot.
- Run Windows Memory Diagnostic (mdsched.exe) to rule out intermittent RAM problems.
If no software or driver errors appear before the unexpected restarts, the issue is more likely related to hardware stability, power delivery, thermals, or a component beginning to fail, especially on a system that has been in service for a couple of years.
