What games can my laptop play?

I'm looking for games that I can play on my laptop. It's an Advent Quantum Q200. It has 2gb of RAM, Intel Celeron CPU C900 @ 2.20GHz. I want some games that I can play without them being laggy. I don't mind if they're FPS's as I have a USB mouse I just want to be able to play something. Thanks. :)
