Your new PC will come with it's own operating system. Moving the data over simply requires coping those files to the new machine.
There isn't an easy way to move the operating system from one computer to another. When you build a new machine it typically involves installing a new operating system on the new machine.
It is possible by using Norton Ghost but you are really better off installing a fresh OS and the wanted applications, then copying over only the data files, everything you've actually saved. The problem with copying the OS and everything is if you have any problems, big, small or otherwise, in the OS you'll copy those over with it. That would degrade the performance of your new machine.
The best option is to use the OS that came with the machine, remember that the new PC has different specificacions like more speed processor, memory, etc.
If the OS is the same, remember that the PC come with several drivers and configuration files, that the vendor had installed and are specific to the new model and maybe do not exist in your old PC.
About the other things that you have in your old PC, you can only copy the data. Generally the other programs installed in your old machine, has to be installed in your new PC again (you must verify if the new machine run the programs - compatibility).
