Well, let’s get it to the point, no spammage crap please.

Dell Latitude C610
processor is a Mobile Intel(R) Pentium(R) III CPI - M 1000MHz
512 mb of ram
windows xp professional

i have tried anti virus, disk cleanup, cleaning registry, and my laptop still runs slow, it’s pretty old.

what should i do?

i use my laptop to play games such as "GunZ:The Duel" should i just end up selling the laptop and buy a newer one, or get more RAM for my current laptop?
