I've had 2 samsung galaxy tablets and each time I inserted the earphones the tablet made a loud annoying noise and the page would either freeze or go blank. I'm unable to turn off either tablet so I can try to reset or restart.

Welcome to Android Central! Which tablet models? Do those earphones work in other devices, and have you tried other earphones as well?

To force a shutdown, press and hold Power and Vol Down for about 20 seconds.

Hello, there are two possibilities.
One is that your earphone is a bit problematic, and the other is that the shrapnel inside your earphone jack is deformed, causing poor contact after inserting it.
If there is no noise on other tablet devices, it may be a problem with the tablet. If there is, it is a problem with the earphone. I suggest you take it for repair.
