All the net homos keep saying to check your memory directly; clean it switch it out, but that can't be it, man.
Sound's like a bad dll, something missing in the registry, or a few people who HAVE had success resolving the problem removed a buggy program that was likely sharing resources with IE. Possibly another damn shared dll that's conflicting with IE.
Try terminating a few startup programs running in the background, possibly some services related to those programs. If that doesn't work, pick your, uh, goofiest app you have installed on your computer (no not your games, although you never know) and uninstall it. Then run IE.
