Hi Atin,
You didn't mention the version of Office or Windows you're using.
You may want to try using Start=>Search/Find and delete the files
you find with file name string *.do*;~$*.*
(close Office apps first) then try starting one of the Office apps.
That will cleanup some left over temporary files.
If Office XP/2002 or higher, you can also try the Office safe mode
after that (hold ctrl key when starting Word) to see if that works.
If so, you may have a conflict between Word and another program.
==========each time i try to open a file the dialog box appears but i am unable to select a file ...the program hangs and displays not
responding..be it outlook, word, frontpage <<

I hope this helps you,
