What things are needed on the computer to play world of Warcraft
Generally any computer with a large enough ram, processor and video card can run World of Warcraft.
As far as operating systems go, you need Windows or Mac, although with some major tweaking and lots of hard work, you can run it on Linux.
If you are having problems running it, make sure you have updated all your drivers for your computer.
