Packard bell? Geezuz...
What is the model number or type? Also what are the specs?
Also, where are you located? EU? or USA?
And you say you've been here:
http://www.packardbell.com/ and selected SUPPORT, entered your COUNTRY and SERIAL number and so on... They should be your first step in recovering your computer.
There is also a Packard Bell forum here:
http://forum.packardbell.com/en/ Which will most definitely be of more use.
