Actually, after scanning the whole threat, I think your problem is some soft in your computer block wamp, even after uninstall and reinstall, so if you don't want to re-format hd, better get a new one (right now Staples has external 60GB for less than 10 buck) then only install windows and wamp, and they must work, then install back your soft 1 by 1 to find out which 1 is the cause.
Have fun,
