If your old PC died because of a bad disk, then you have very little chance of recovering the data from it.
If it died for another reason, you may well be able to add your old disk to your new PC and recover all the data from it.
I can also recommend disk backup software. I use Acronis, and for the cost of the software and a USB drive, it's paid for itself many times over.
