No, never tried using a different browser, I think I'll give it a try because I have been using Google Chrome a long time. And I'll look into getting a USB, thanks for the link, the ready boost looks like something I'm willing to try.
Also, make sure that you've cleared history on Chrome. If you've never done that or haven't done it recently, it can contribute towards browser slow down.
I normally don't use Chrome, but it doesn't appear to have an option to clear history on exit. Chrome users - you can correct me if I'm wrong. Firefox does have that option, however, so you might want to try that.
