In other words, is it possible to make a game that requires a 1Gh processor to work on an 800Mh machine? If so, how do I do that? I'm trying to run Colin McRae Rally 2005, but my computer is too weak, and the graphics card in my computer(nVidia GeForce 2 MX400) is not supported.
Sorry, but that is not possible. You need to meet the game developer's minimum system requirements for the software to run properly. Weycraze
The 800MHz might have just been enough, but that graphics card will hold you back in most games. If you want the computer for games, it might be time to be looking at a few upgrades, or new system.
