HP Compaq Pro 4300 Small Form Factor PC fan comes on but computer does not. We had a power outage and now the computer power supply fan comes on full force but the computer will not power on and no lights come on.

Greetings,

Welcome to the forum.

I am not a HP employee.

 

I would guess a power surge has occurred.

 

This surge may have damaged the power supply, the motherboard, or a component connected to the motherboard.

 

Component failure has occurred.

 

Regards
