WoW Freezes every 15 mins!

[Sixers2329]

I've played wow on the same computer for 3 years without any problems. I went on vacation a week ago and got back yesterday. I booted up WoW today and it keeps freezing every 15 mins or so. By freezing I mean completely, no music, no mouse movement, not being able to alt tab or anything. I've tried repairing and a bunch of all those little tricks in the books. I think it is something wrong with WoW because I see alot of others having the same problem. (Happens on all private servers and retail servers.)

Thanks guys.

PS, I don't think it is my graphics card because I can run gmod, css, hl2, and bf2 smoothly.
