You need to understand that the way one "reset it to factory settings as it was when it was new" is by reinstalling Windows. So in order to do that you need either a Recovery Partition on the Hard Disk or a Recovery CD(s).
If you do not have either then I am afraid that your only option is to buy a set of software. For more help try Packard-Bell support on www.thetechguys.co.uk .
