Wow won't Log out or exit properly

Hey, I'm not sure when or what has caused this. sometimes its not that big of a problem but that's only for like 2-3 days, but when i attempt to log out, or to exit wow, the computer tells me wow has quit responding. though when i go to "processes" its using up 50% of my CPU. If i log out, it will sit there until i "disconnect" from the server. when i exit wow, it will more or less do the same thing but 10+ minutes later it will close. If i force close it, i generally loose all my setting, information and so forth for all of my addons. as if i did a fresh install of them.

i have tried disabling all of my "outdated" addons and the most recent ones I've added that came soon before i had these problems. no change. I've looked threw some of the information on here, but they are all old and in response to updates in the past. Recently i was opted in for the SC 2 beta testing, and so installed it, and it did not work. and so i have gone to the dell site to update my graphical things. i don't know if that may or may not have effected it, or aggravated it or had no effect at all, as i do not recall when i first started having these problems.

This problem happens no matter how long i have been playing wow. weather a brief hop on, or on for many hours.

after disabling all addons, it still was a 15 second delay for logging out of the character, so not too bad, but it still took wow 2 minutes to close from the log in screen.

-nosound did not seem to effect this at all.
