WotLK Constant Freezing

[Baleful]

Hello, I've been having this problem for about a month. My game is constantly freezing from 2 to 10 seconds and sometimes permanently in raid until I close the game via task manager. Everytime I do something such as open the map, target someone, open talent tree, the game freezes. Today I reinstalled windows in hope that it will put an end to it, but it was in vain. I'll put some info of the PC I use, if you need additional info, do ask.

i5-4210U CPU
GeForce 840M GPU
6GB RAM

There's definitely no temperature problem and I have the latest GPU drivers.
Thanks in advance.

10k gold that is some of addons blocking/freezing.

I forgot to mention I tried to delete my interface folder and it did decrease freezes outside of raids, but the problematic permanent one that occurs while raiding was still there.
