WoW Classic freezes, sound stutter, interface/animation delay

I am having the same/simular issues. at first my pc would just randomly freeze, where i could move the mouse, open start menu, but nothing else. could not click on anytihing at all. So force restart was the only solution. this would happen maybe once pr day. But today the game has crashed 3 times in a row while killing murlocks outside of theramore. Suddenly animations and sounds are gone on some spells. backgrounds on chatbubble, tradewindow etc is gone.i cant see other people but i can hear them, and then my PC crashes. sometimes the sounds and animations just catches up looong after i have killed something.
i literally heard a mage make water right next to me just now but i couldnt see him. i saw a mob get attacked but no one was there.
Ive allso experianced micro freezes when traveling, zonechange etc, and i can see a glimpse of a white line down in the left corner with some command line on it. but its so quick that i cant make out what it says.

My suspicion was that my SSD is about to die. but since you are experiancing the same thing, maybe not ?

My specs are
Gtx 980ti Sli
3930k cpu
64gb ram
2560x1440 165hz G-sync. running on ultra setting with 122% resolution scale.
And the game is on a samsung 500gb ssd. wich allso has windows on it.
