One thing you can do to increase performance a little is to add more memory. Your machine will take up to 2 GB so you would have to take out what you have, since you only have two slots, and add two new sticks. It should give you a little boost on many apps, but you will have to decide if it is worth it to you to put that much money into your aging system. Might be better to look for a Black Friday special - a new system for $250-300, if you can afford it.
