WoW crashes problem

I am playing on Cata expansion (client downloaded from your website).

As far as I know I've been getting random crashes since long time and I never knew what causes it. Its always "application has stopped working" but no error appears. I tried to check few addons (Recount/Skada, nameplates, MoveAnything, Prat) and turn them off, but crashes didn't stop.

And list of addons I use:

All addons are up to date, "Load out of date addons" is turned OFF and none of my addons are red.

Known to me:

Throne of the tides
Stormwind (multiboxer with 20 chars)
Alterac valley

Heard there are alot more... but yes, this happens in the cata realm because of pieces bad code here and there.

For me it feels like it can happened literally everywhere. Also I asked few people and they say they never crash so I don't know.

Btw I am playing on Dx11, with abit lower settings than Recommended. I have stable 60fps (limited it) and VSync off. My computer doesn't have problems to run the game generally.
