My MoP client keep crashing constantly

Hello fellas, I have an issue for like 2 months maybe. My client keep crashing from time to time, by crashing I don't mean the WoW errors, but the game freezing and after a few seconds showing that the program is not responding. I don't think it is some ingame content doing this to me, but client problem or even maybe OS problem, so I decided to ask here first before go doing something like client reinstall or OS reinstall. This crash pop up on different places like, BGs, Arenas, Raids, even in cities like Shrine of Seven Stars or Stormwind, just everywhere can happen, so any help is welcome :)

Could be your addons that are causing the lockups, try disabling everything and see if you stop freezing.
