serious macbook pro issues

[kta24]

So some problems just occured on my macbook pro mid 2015 model today such as whenever I use the volume key to change volume it makes the screen go black then makes me login in again and whatever I was doing before that crashes. Like if I am on Ableton and I use the keys then it would restart and crash ableton. Next thing is when I try to play a media file by pushing the space bar it just says an error occured with the preview of this document but works fine in itunes. And then Logic Pro X all of sudden crashes when it opens and I have tried to reinstall but still same thing happens. This all happened out of nowhere today. I have resetted NVRAM, SMC, and restarted a bunch of times but nothing has worked. This is a 2.5ghz 16gb ram 512gb ssd mid 2015 model. Any help would be great!

Whether it's under warranty or not, I recommend taking it to the Apple Store for diagnosis.

If the apple store is too far away, you might want to try an smc or pram reset, and/or fresh installation of the os.

Can you boot into Diagnostics? Restart, while holding the D key.
Run the test. Are any hardware error codes reported?
