MacBook starts up, then shuts down
I’m not quite sure what happened but I can’t get my MacBook to run. Every time I turn it on, it goes almost all the way thru startup and then shuts down. There’s also some glitchy looking graphics on the startup screen (very very small letters and numbers all over the screen) and I have no idea how it’s doing this. Also, my trackpad isn’t “clicking” anymore. Not sure if the two are related but, what do I do?
