Question HDMI - no signal

[Reso]

Hi, just completed my build & I'm getting no signal on my monitor. Nothing is ever simple is it. My GPU's fans are moving so does anybody have some troubleshooting ideas? The monitor works fine, I have had it for a year.

edit: here's my full system: AMD 7800x3D, AMD 7900xt, 32gb RAM, B650E-F mobo, Corsair RM1000x PSU.

edit 2: this thread has nothing to do with my monitor not getting signal, this issue has been fixed. Not sure why my other thread was moved to this, windows is black screening after installing it - not my monitor not receiving a signal.

As the title says, built my new PC today & went through the motions. It booted fine & there seemed to be no issues from the BIOS. However, after installing Windows from a USB it black screened and nothing has happened since. Any tips or is this a job for safe mode? Thanks

Dumb question???
Did you connect your monitor to the motherboard and not to the gpu?

Nope, it's connected to the GPU, the BIOS booted fine initially but windows just blacks after its installation.
