Hello, I bought a new pc, and now i get completely pc Freeze in dungeons and raid, nowhere else, just there, and i cannot do anything, have to restart my PC.
Tried reloading interface , updated video card drivers, and alot other things, but nothing helps, Please if you know anything about this problem, answer this <3

what do you mean with "reloading interface" ? just tiping /reload on chat?
Try to play a dungeon/raid with all addons disabled.

Also, in which moment your game freeze?
as soon as you enter in dungeon/raid?
during Boss fight?
