what can be causing my Internet Explorer 6 to hang CONSTANTLY?

[Foundation]

when I have two or three browser windows open, sometimes it hangs. I can't scroll or click anything. This happens every ten minutes and I am tired of alt ctrl del>end task. Is this a hardware conflict? how can I fix this, thanks....
