You need to replace the video card. If the video card is part of the motherboard (integrated), you will need to add a discrete video card (PCI-E) to one of the slots on the motherboard and disable the integrated card in the BIOS.

If the video card is a discrete card (already in one of the slots), you will just do the same thing as above, replacing the old one with a new one and installing the drivers.

Best to uninstall the video drivers before disabling the built-in card OR removing the separate card.
