the PSN doesnt say how fast your comp runs (PSN is a unique number in all computers). All it does is identify your machine as you - it's just a serial number built into the hardware. It was supposed to be used to identify your machine as you on the internet (as no 2 PSN's are the same) for online purchases, etc but then Intel later figured out that it was a good tool for hackers to identify you with.
So Jerboy, you're 17 years old, well isnt that interesting (your sig).
