Stuck On Spinning Dots After Update

[PhoenixMunro]

Hey,

I've just updated my Windows 10 on two PCs last night. This morning I came to turn them on and both got stuck on the spinning dots black screen.

My media PC took one force shut down restart to log back in, but my brand new beast took 6 of them to log in.

Ctrl Alt Del didn't do anything on either machine. Now that they're both running, the updates look like they've installed correctly but I don't really know what I'm looking for.

My media PC has had this happen a few times, and my new beast has had it happen once before, but never this bad. I legitimately got enraged and kind of scared my boyfriend. I just don't know what to do to stop this happening again.

Help??

Currently attempted:

Updating GPU Drivers (After a bunch of hard reboots it booted up okay)

Got to blue option screen,
Startup Repair couldn't repair
Went to Startup Settings, booted into Safe Mode and disabled inessential boot up stuff in Task Manager

Tried disabling Fast Boot

Unplugged power, waited 10 minutes, plugged back in (After a decent wait, computer has booted up okay)
