PC has Startup Sound, but No Display

So I done a regular shutdown last night and this morning it doesn't display anything on boot. My Nintendo switch shows up with the same HDMI cord. Removing the GPU and trying the mobo doesn't display. Using an old GPU doesn't display. The monitor gets no signal from my desktop at all. No bios. All the while, I hear the windows boot up noise. I tried removing CMOs battery for 15 seconds to try to get it to switch to mobo display but that doesn't work.
