first thing, CPU is the Central Processing Unit. On your PC (what you intended to say), it is on the Left side center of the motherboard.
You will not be able to play skyrim on that laptop.
Upgrades: CPU: Should be able to upgrade to a P4m 2.6 GHz, assuming it is the original 130 process. Still wont meet skyrim specs. It requires Dual core 2GHz.
RAM: DDR 1GB max. You need a minimum of 2GB to run skyrim.
GPU: You are running a AGP 4x Mobility Raedon (probably a Raedon 9000 or 7000), this is not upgradeable. And does not meet skyrim specs.
