Not checking is akin to a car that won't start, and tearing apart the entire fuel system, only to find it was just out of gas.
1) Make sure the receptacle the surge protector is plugged into, has power. Surge protector Power On light should be lit.
2) Check THE receptacle in the surge protector, that the computer itself, is plugged into.
Have had a number of expense surge protectors, where just THAT receptacle was bad.
("Hmmm, surge protector Power On LED light is lit. Monitor, printer, sound system, and router plugged into the surge protector has power. Should be good to go.
NOT!
Plug a table lamp, or similar device into THAT receptacle.
Make SURE it has power)
Surge protector, and receptacle in surge protector checks out?

In order to guide you in this procedure, I need to know the computer manufacturer name, and Model Number.
On a desktop computer this will be located on the Back of the computer tower, (Next to the Windows product key), or up on the side of the tower.
Some models have it where there is a door you open in the front, and the product number, or model number is located there.
