Hmm... What does nothing mean exactly? Did your monitor turn on during boot? If so, did it turn off again at some point or did it display a completely black image?
Since the mobo connection worked (which usually uses the integrated GPU chip on your CPU as far as I know), maybe it was an issue with your gpu? Or the connector or something?
I once had a broken setup where got stuck on a black screen, unable to switch to a tty. If I started spamming CTRL+ALT+Fsomething right after Grub was done, I managed to escape the black screen before it appeared, maybe you could try spamming the key combo early on and see if that opens a tty for you. If that is the case then you can be pretty certain that the problem is related to your desktop environment.
Nice! Since your installation is showing similar symptoms to my installation when I updated my nvidia drivers a while ago, I'm just gonna tell you how I fixed my issue on my computer, and maybe it's gonna work for you too. If you want, you can try this:
Boot your PC. After your Motherboard is done showing its logo or whatever it shows, you should see grub. If you press 'e' before grub proceeds to boot into linux, you will be thrown into a simple editor that will let you temporarily change what grub boots. There is a line with the kernel image and arguments, it probably starts with 'linux'. Go to the end of the line (line might span multiple rows, so end of line might be on the next row) and add this:
Then press F10 to boot. That's it.
This fixed the issue for me. If it will fix the issue for you as well, you can consider adding it to your kernel parameters permanently or making sure the nvidia kernel module gets the parameter by other means.
Hope this helps!
