Account issues

          I have been having some issues with my account with the new expansion. I find my self getting stuck when I get close to Dread Wastes. Not only do I get froze in my game but my computer also freezes up and then I am forced to hard shut off my computer. I then could not retrieve my character and had to get on my old computer to get him out of the area. I submitted a ticket to Blizzard and after two days they finally responded. I was told to delete my Cache, WTF, and Interface folders. I did this and still am having the same problems. I have replied to them that I was still having the same problem and was told that I need to make sure that my graphics card was up to date. I again replied to them need explanation on how to do so. I don't consider myself computer illiterate but there are programs that I don't understand. I am now awaiting for instructions on how to do so. Hopefully someone reading this will be able to help me. I didn't purchase this expensive gaming computer to have such problems. For some reason I can't get my Java to work as well. Please oh please someone help me. Also for any readers, post some cool screen shots. I always enjoy to see what others are into.
