Razer Blade 15 (Early 2016) Won't Boot Past BIOS

My Razer laptop can't get past the Razer logo, it just shows a black (but still on) screen. I can access the BIOS, but that's it, and there aren't any BIOS settings that fix the problem. I have tried:

• Using Windows' Automatic Repair service, but it shows a black screen after "Preparing Automatic Repair"
• Restoring user defaults in the BIOS
• Booting from a recovery USB, but it shows another black screen after the logo
• Booting from an Ubuntu installation USB, but I am stuck at the Grub terminal
• Replacing the battery
• Replacing the SSD with the one from my desktop
• Reformatting the included SSD

I haven't yet found any threads where the problem wasn't fixed via one of these steps, so is there anyone here that has?
