How can i remove a video card from my computer so that it goes back to using the video chip it has.?

I have an Emachines computer which i upgraded with memory, a new hhd and a new video card. it's worked for years. Now the video card which i had installed is failing and i dont really have the money to get a new one or get it fixed. I really thought i could just go back to using the video chip that i used before i installed that video card, but dont know what to do. Can anyone help me?|||go into the bios and select your internal graphics card and then take your other one out.|||Just pull out the card and plug the monitor into the VGA port on the motherboard. Then re-install the graphics drivers for your eMachines model. It's really that simple.|||You need to get in your bios. That's the screen that comes up when booting up that tells you to press certain keys to get into you BIOS. Once in bios you can choose the video chip on the mother board to use for your video instead of a plug-in card.
