Among boot problems, the “powers on but does not boot” symptom may be related to boot file corruption or storage device issues. Distinguish between the POST stage and the Windows startup stage, then check in that order: external device, boot settings, and recovery environment.

First look for CPU, memory, and disk bottlenecks in Task Manager and check startup programs, storage space, and temperature.
