Ossy's right. It's better to use an emulator on your desktop. The reason is that only laptops made specifically for hardcore/high performance gaming can run ps2 graphics because of their NVidia or GeForce graphics card. My laptop uses Vista Ultimate on 2gb ram and it stil can't work even with some games such as Need For Speed Pro speed. It'll just drag. You can try the N64 emulator and play Mario Cart instead.
