You shouldn't even be running XP with that little RAM. Your system must be painfully slow.
"i used a popular cLeaner"
Which one? CCleaner is an excellent cleaner & is safe, but it can't protect the system from an overzealous user on an add/remove rampage. Why are you attempting to use Directory Services Restore Mode? If anything, you should try Safe Mode or Last Known Good Configuration. However, if you successfully trashed Windows, it will probably have to be reinstalled using the Repair Installation method.
