I gather you are "Josh", and the Asus support forum was no help either lol.
Anyhow, you can try to identify what socket you have by comparing what you see with pictures of the various sockets a P4 came in. Then you could buy a faster Pentium 4 that fits that socket, and pop it in, see what happens.
And now you have some insight into our reaction to Vaios. When you want to do something like this, they want you to buy a new one. And that's only one reason.
