Laptop help !

Let's look at a different situation:
Ask this question in a car guy forum - How do I make the car go faster?

Is it a Mustang?
A Corvette?
A Honda?
What have you already done to it?
Is it a 73 pickup truck with a lot of rust?
How much money do you have to spend?

I could go on....
 
It is obsolete. You simply need to buy a new laptop. Laptops are currently on sale now so good deal can be found on the web and maybe in some walk-in stores. A new generation of laptops are coming out soon so retailers are trying to sell off existing inventories. Example:

Gateway NE56R34u Notebook Intel Pentium B960(2.2GHz) 15.6" - $355
Pretty inexpensive and basic laptop. More powerful than your old laptop. But weak compared to more expensive laptops.

ASUS K55N-DS81 Notebook AMD A-Series A8-4500M(1.90GHz) 15.6" - $380
A better laptop than the above for games

Lenovo G580 (59359688) Notebook Intel Core i3 3120M(2.50GHz) 15.6" - $399
Pretty good performance overall, but does not play games as well as the above Asus laptop because the Intel HD 4000 graphics core is as powerful as the Radeon HD 7640G in the Asus laptop.
