Does your Windows PC shut down or restart without warning? There are several potential causes behind that. For example, it could be a software/hardware conflict, overheating, or hard drive error. This troubleshooting guide will outline multiple solutions to fix auto-shutdowns and restarts in Windows 10/11.
