Answer
Record the stop code, disconnect new hardware, install supported updates, then use the matching Windows recovery option if startup fails.
Record the failure
Note any stop code and whether the restart follows a new driver, update, app, or hardware change.
Remove recent variables
Disconnect nonessential hardware and uninstall or roll back the recent driver or app associated with the first restart.
Update and scan
Install Windows and manufacturer driver updates and run a Windows Security scan.
Use Windows Recovery
If Windows cannot start, enter Windows Recovery and run Startup Repair. Use System Restore or another matching recovery option only after backing up data.
Retest the same workload
Run the workload that previously triggered the restart. If another stop code appears, record it and the time of the restart; do not combine more driver, recovery, or hardware changes before checking that evidence.
Video walkthrough
If it does not work
- Repeat the workload that previously triggered the restart once and record the time, any stop code, and the last app or device in use. Do not apply several driver, power, and recovery changes between tests.
- If restarts continue outside one app or Windows reports hardware errors, preserve current backups and give the PC maker the stop code and timing before changing firmware or replacing components.
