Processor Thermal Throttling (Event ID 37/196)

What this error means

This high-severity issue affects the processor (CPU). This diagnosis detects processor speed limitation events (Event ID 37 or 196 in the Windows System Event Log). The CPU reached its thermal limit and activated throttling to prevent hardware damage, resulting in system slowdowns or shutdown warnings. It's most often caused by dusty radiator and poor cooling. Use the steps below to track down and fix the cause.
