Constant Crashing

I am not sure what all I can post to help describe the problem and the steps I've taken, but I went through and tried all of the online "solutions" I could and I contacted Adobe support. They've looked at my computer virtually and were not able to help.  

To back up, I started having problems with After Effects crashing and being very unstable around two to three weeks ago. I found/tried all the possible solutions I could and I contacted  Adobe support. No solution.

Then, by fluke, I did something like revert Media Encoder back to another version and got an error message and had to reinstall it (sorry, I did not make notes and I've forgotten what exactly I did). Miraculously, AE started working correctly again. Today, after restarting my computer, I tried using AE and ran into the same problems again. I tried to replicate what I did last time but it hasn't worked so far. 

My computer is fairly new with a decent graphics card (that also updated a few weeks ago - there was an error message in AE telling me to update it). I am tired of fighting with it when it seems to be a common problem based on what others have posted. 

Today, I tried unistalling AE and using an older version. Of course my files won't work with that version, so I had to go back to the latest one, 23.0.

I will reach out to technical support again, but they did nothing the last time and wanted to get rid of me by saying, oh look it's fixed and then it would crash (they did this a few times and finally just had to go). 

The problem is pretty basic, I will be editing a video and adding text, the text will stop working and the video will stop showing, preview doesn't work. I try and do something and it says not responding then when I X out, it asks to send an error report, which I do.  I can't work in there at all - it crashes within minutes of loading.
