Hey Neway,
Welcome to PCHF. We have a fabulous hardware team here. I am sure that they will be able to help you figure out your problem.
Unfortunately, hardware is not my area of expertise, however, I can see some questions, which your answers to, will help the hardware gurus to help you.
Can you please post the exact specs of your PC, including
PSU?
Can you please verify that all cables are connected correctly and everything is seated properly?
Do you get ANY response when you attempt to turn on the computer? Clicks, beeps, anything?
Look forward to your reply,
TTFN
LGW
