Ok, since it works in the administrator account, see if when you create a new user account it works in it to try and avoid doing a clean reinstall. If it does, then you can copy the files you want from the old user account's C:\Users\(user-name) folders into the corresponding new user account's C:\Users\(user-name) folders. After everything checks out, you can delete the old user account from within the new one or Administrator account. Repeat for each old user account that the Recycle Bin does not work in.
