@beta2k,

There's definitely a slew of issues going on here. First, I would take the SSD out and run a malware scan on it from another computer. I think Malwarebytes can scan external drives (maybe?). In regards to the RAM, with the BIOS beeps, slow speed, and Finder issues, I would just go ahead and get new RAM even if it technically boots up with those sticks. Get [https://www.crucial.com/compatible-upgrade-for/apple/macbook-pro-%2813-inch-and-15-inch--mid-2012%29|Crucial] or Corsair RAM for Mac, I have good luck with those on the MacBooks. With the power issue, either the battery is shot, or the Magsafe DC-in board is. Either part is replaceable, with the latter being far more difficult, as you can see by the guide below.

If you’re handy and comfortable and decide to go with the Magsafe DC-in board replacement, you might as well replace the thermal paste on the CPU at the same time. This will improve thermals and speed.

In regards to the random pressing on the case and causing a restart, I’m not sure what’s causing that… You’re probably going to have to do some further investigating to see what components might be being pressed from the outside of the case and see.

If this helps, let me know!
