Resolve Windows 10 related issues for your HP computers or printers by HP Windows 10 Support Center
@Tayler1 Welcome to the HP Support Forum!
I understand that you are unable to see anything on the screen after the power outage.
Step 1: We will first perform a hard reset.
Step 2: Connect the power supply and turn on the PC and see if fixes the issue.
Step 3: Secondly, check if the brick on the power supply is getting warm.
Step 4: If it is not then it could be a power supply issue because of which the PC is not powering on.
Let me know how it goes and we can take it forward from there.
