I am trying to refurbish my sisters old HP pavilon ze4125 laptop Amazon.com: HP Pavilion ze4125 Laptop (1.4 GHz AMD Athlon XP 1600+, 256MB RAM, 40GB hard drive): Computers & PC Hardware. Im not sure what she has done with it but it has become increasingly slow in usage. I was wondering if anyone has any suggestions on what I could do to boost performance via software first, and if nothing is available then I would think that the increase in RAM would improve on this problem area. But any suggestions and or solutions are appreciated.
