It looks like the PC needs repairs. There are many "help me fix my PC" posts on the web so here we have an unknown PC, no backstory so what to do but say it needs fixing.
Google "The Dead PC" for prior discussions.

Hello all,
Today I attempted to turn on my desktop, and the monitor displays a blank black screen. I have tried connecting the desktop to a different monitor and it does the same thing.
The desktop turns on, fans run, and sounds normal. What are some things I can try to fix this issue?
