sorry for double post, but i really don't like hitting the edit button. and you posted 2 seconds before me.

haha you disabled system restore... good job, it improves your speed, but bad because the only way to fix it now is to do a clean wipe. well unless you got a spare computer you can work with, even so, its tough
