Sorry but it's probably nothing to do with pc speed, I have a 2.0Ghz Pentium 4 with 1Gb of ram, right now I have 10 tabs open in Firefox 2 all loading different sites & I'm able to type & fire this reply off with no trouble.

Wouldn't you know it, soon as I shut the other tabs this site starts running like it's up to it's knees in mud.
