not sure what os your old pc has but go to this site http://windows.microsoft.com/en-us/windows7/products/features/windows-easy-transfer
download the correct software for you old os. this will collect all you old files settings .pst's and Customisations.
it will ask you how you would like to transfer them i would suggest a thumb drive.
now take the thumb drive to your new pc and click start > all programs > accessories >system tools > windows easy transfer
suggestion when you save the file to your thumb drive create a folder and put it in that, every now and then if screws up if it is not in a folder and wants to save or restore the files from floppy disks.
