Screen freeze while using certain abilities - WoW

[Anaeska]

need some help from dear community. I have WoW installed on my iMac in the bootcamp mode, i.e. in the Windows 7. WoW has been running flawlessly till lately. I run WoW at Ultra my configuration can be found below. The problem I have been having is when I use deterrence on my hunter the screen freezes and then resumes in 5 seconds or so. Same thing happens when I use nitro boost (increased run speed) on my belt and glider thingy (parachute on cloak). I am an engineer.

This rare/strange phenomenon only occurs while I am in combat. When I am freely wandering in the world doing quests or fighting Azorethians I can use the abilities and tinkers just fine. Issues only happening in raids. A while ago this kind of happened when someone or me used stampede ability (hunter ability).

With my problem posted; I ask the community for help and feedback in eradicating this issue so I can use those great abilities in raid. I don't care much for other issues, but not being able to use deterrence is a big drawback while raiding.

Sounds more addon/WTF folder related then PC related if im honest, delete WTF/CACHE/INTERFACE, boot wow up cleanly and see if it still occurs. I know its the standard responce but it seems weird for it to be the PC.

Thanks for that. I will tr this as soon as I get home.

Be sure to backup your WTF and Interface folders though so you don't lose your addons as well as the settings for them.

I agree with Arbiter.I have no backup available right now, but my trouble is solved. Hope yours was too.
