Lag Problems?

[Baaja]

Hey fellas this is my first post here, and i got a big problem! It is about lag, i know i doesnt have to do with my internet connection. But my hardware is kinda crap, im on a 3 year old comp and it has a 1,7 gig processer, 256 ram and an old nvidia video card...ive put the wows res to the lowest, ive turned of the firewall, tried to remove all ad-aware and spyware etc...ive defragged the disc an all, but is there something else i can do?...i mean, can i remove those windows apps that run in teh background, if i can, can u tell me how. And whic should i remove?? thx alot

You seriously need to get more RAM.
512 mb or 1024 mb would do it, and you can have a crappy graphics card just it is at least 32mb in it
And you run WoW On Minimum Graphics with almost no effects

Minimum for processor is 1,5 GHz so that's cool!
