Ever since 5.4 patch was released, WoW would freeze on me randomly, I would have to alt tab out and End Process. I disabled all addons, lowered video settings. Even went as far as reinstalling windows 7 and WoW. It still randomly freeze on an average 2-4 times a day. I could be standing still in Org or raiding in SoO. Any ideas would be appreciated. This is a Win7 machine with intel i7, 8GB ram, AMD Radeon HD 6700 video card. Updated drivers. WoW is the only program/game that locks up.
