PC won’t post anymore

As title says my PC won’t post anymore, was trying to install windows from usb and it was failing saying it can’t be installed and giving me an error code.

Tried installing my M.2 from my current laptop and it didn’t post. Installed the new M.2 back into the mobo and my pc just won’t post no matter what I do, re installed gpu, cleared CMOS multiple times and let it sit unplugged for 20+ minutes and tried restarting but nope. Just gives me No Signal from both the DP on the gpu and the HDMI from CPU on both my monitors (tested seperately) whilst the pc turns on and fans spin.

I’m at my wits end this is way too much trouble for what should be a quick and easy process.
