How to fix Minecraft Bad Video Card error message?

Alright i have tried everything, turning down the hardware execration,trying to update my video card EVERYTHING. I'm running Windows xp. Im not sure witch kind but its made by emachines so that might help. Can anyone give me a link to a video card i can download or maybe give me some advice?|||Did u try running it in the browser and a video card is a piece of hardware but u might need to update the drivers go into ur cmd then type in dxdiag to find the card then go to that cards website and down the newest divers|||You don't download a video card. Getting a new video card actually means buying a piece of physical hardware (the video card) and installing that into your physical computer. That said, you wouldn't need a too powerful video card to be able to run Minecraft, an Nvidia 8400GS would be a cheap option.
