I am sure not a computer whiz... but does it help at all to click your "Refresh" button or "Compatibility View" button? Both are up in the bar where you type in your internet address... both are to the right of the magnifying glass.
Here is a link to Microsoft (if that is your operating system).
I also use software to delete all "cookies" that websites save to your computer. It seems like if you get enough of that junk, it slows it down.
