Hello Jen!

Try this:-

Turn the machine off by holding down the power button

turn the machine on and instantly hold down the cmd, alt, p and r.

Hold these keys down while it opens up to the apple logo, it will go black and boot again, let it do this 3 times and then when it starts again, let go.

See what that does :)
