[Help!] Updated my kexts and now my PC won't load past post

I have a skylake, nvidia gpu if that is relevant. Also followed this community's vanilla guide for initial install.

I updated: clover configurator, appleALC, lilu, whatevergreen then restarted. Now the PC won't load past post and I can't get into the boot menu (F12) or bios setup (DEL).

Do I need to remove the Apple SSD? I have two separate SSDs (Mac/Windows). I hesitate to remove the Mac SSD because it's an m.2 and right under my CPU cooler meaning I have to take off the cooler to get to the m.2.

I have a backup bootable SSD, all my files backed up and so I won't lose anything, but none of this helps me if I can't load into the boot menu or bios screen.

I've never seen anything like this before. Please help!

EDIT: Everything was working fine until I updated my kexts. I did so simply by replacing the kexts in my EFI/Kexts folder.
