Weirdness while booting, and now ubuntu wont recognize my 4090

I just built a new computer. Everything was working wonderfully until I moved it upstairs to my desk.

I couldn’t get it to boot until I plugged the HDMI cable into my motherboard, it booted, and then I powered it off and connected it to my gpu. Worked fine then. I follow this procedure every time I need to restart my pc. It usually works fine.

I just rebooted my pc, and went through that whole task again, but now it won’t recognize my gpu. I have a RTX 4090 btw. Nothing changed, no new installs or anything. Really need some help here fellas, thanks!
