The command you are looking for is known as Reboot Even If System Utterly Bad - REISUB.

So what you need to do is:

Press ALT+Print Screen and then enter the following key combination. REISUB

More details of the command are:

R: Switch the keyboard from raw mode to XLATE mode

E: Send the SIGTERM signal to all processes except init

I: Send the SIGKILL signal to all processes except init

S: Sync all mounted filesystems

U: Remount all mounted filesystems in read-only mode

B: Immediately reboot the system, without unmounting partitions or syncing
