Application
Application errors.

OS, drivers, services.
Security
Authentication/security activity.
Setup
Installation/update activity.
Services
A stopped service is not automatically a reason to restart it. First investigate why it stopped.
An Event Viewer error appears exactly when the website failed. Is it automatically the root cause?
No. It is correlated evidence. Confirm with other logs, services, IIS/Plesk and recent changes.
