heyyyy ...THANKS for replies.. it's time for reading deep about this.. Tbone your suggestion is the best but sometimes time is short for formatting... and re-install everything and configure your softwares.etc you know what i mean.. also could be done by cleaning the XP files and leaving the rest archives/download files, music ..etc untouched ...but also takes much time.

btw any other tips or suggestion about the topic are welcome as well...

Best Regards!
