Remotely powering my gaming Pc off and on with Arduino

Lately, I've had the crazy idea of somehow remotely powering on my gaming pc with a fingerprint scanner connected to my Arduino Uno. I'm relatively new to Arduino so I'm seeking guidance on how I might be able to accomplish this goal. I'd appreciate any advice I can get.

Cutting off power to a PC in any manner similar to that of pulling the electrical plug from the outlet is a very BAD idea!
