IE7 and Windows Exp. : White screen, can't navigate from root, help!

[ElNiNoSt0rM]

As the title implies, after a few hours (or less) of using my computer (normal usage. No spyware sites, etc.), my internet explorer will not navigate past the homepage. When doing so, it turns to a white screen (within IE) and the status bar disappears, at which point it hangs. At the same time, using Windows Explorer, I can't navigate past the root directory (where you see C:, D:, etc.). It automatically boots me back to it. It's not FROZEN, per se, but it just keeps kicking me back.

Windows defender didn't pick up anything unsual.

Any thoughts?

Well, get something better than windows defender first. Superantispyware and avira antivir are what I use. After you scan with those, check to see if any windows files are corrupted
(if you have vista) here

and dont double post
