Then, after an indefinite period of usage, the crash will come again. However, recently I've found that if I plug it into the charger when it's in that state, my MacBook immediately starts booting and functioning properly. When it's in that state, I can wait an indefinite amount of time before it will start up again without issue (the 1-2 times this worked, it crashed, I pressed the power button, got the 3-beeps, shut it down, and tried again about 1.5hrs later and it booted normally). I've read that this indicates a RAM issue however, there's more.

Now, about 3-4 months after resolving that issue, my MacBook will enter a particular state: it will randomly crash, and on restart stay black screened and beep 3 times no matter how many ones I try to reboot. This issue was resolved by removing the second RAM stick from the bottom slot, and using only one stick in the top. I used to have RAM in both slots working fine for over 6 months, but then suddenly I had an issue where the screen would distort with vertical lines and crash when I picked up the device from below the track pad area, or put pressure near the trackpad (even just normally resting my hand to type). I currently have 1x8GB of RAM in my MacBook in the top slot. I've been battling a potential RAM issue for some time now, but a recent discovery has led me to seek more answers about the specificity of the RAM issue.
