Files on the gnutella network are not stored on any server / site. Files are shared between users like yourself.
Do you have any idea what the problem with the old computer was? If the hard disk drive failed then you have problems. Generally drives gradually wear out ... and although might fail occasionally might still work on odd occasions, at least to get rebooted for long enough to recover 'some' personal files. It is possible to get professionals to recover a % of files from the drive for you, but that option is generally highly expensive.
