I am sorry, but I do not understand how 5BMs is a lot of memory unless you have like 64MBs of RAM and running Vista, which is impossible...
Unless you are running Vista, which I hope for your sake you are not, your windows is only using 30-40MBs of RAM...WoW uses about 25-30 depending on your config...and even with a ton of addons, and I mean a ton, they will only use another 20MBs...so, at max estimate you are using 90MBs of RAM...In order to play WoW BC, it requires that you have 512MB of RAM on your system...so seriously, what is the problem here!?!?!?
Scenario 2: You are running Vista...well...I guess everyone has their own opinions...Vista uses about 500-700MBs of RAM, Also about 256MBs of your GPU, so if you have Vista, have a GB of RAM, and 256 GPU, you are in some major trouble...Actually, did you know that if you are running Vista with only 256MB GPU, only like 10MBs of your GPU goes towards WoW, because that is all WoW needs to run...LOL...anyways...
You people saying it is a memory problem, if you are on XP, I don't wanna hear it...It is a dead excuse...and, don't take this as me being a jerk, I just wanna know if you have actually taken the time to look at the facts...
