Try only loading basic and see if U get same error:
Start >run>msconfig>Load basic.....click ok
Does it do the same on every user?If not, it would be easier to just copy your documents and desktop to a new user.
Or it it's user profile related, U could download UHP clean. U could try downloading and let it run as a service.
Or try removing some of your services from msconfig that U don't need and aren't vital and try again.
