Hi @oluwatobiidowu

A dusty fan and dried thermal paste on the CPU can contribute to the PC shutting down to protect the CPU from overheating and being damaged.

Check if the fan needs cleaning and also if the thermal paste on the CPU needs to be refreshed.

Here's the ifixit HP Elite Mini 800 G9 Teardown guide and also the How to Apply Thermal Paste guide that will help you access the necessary components i.e. fan and CPU
