Is there an adapter that will hook up a pci express video card to a pci slot?

I bought a pci express x16 video (graphics) card for my emachine T2042, that has been upgraded to 1g or ddr. Low and behold, I need a pci card. Is there an adapter that will allow me to plug the pci express card into the pci slot, or am I stuck saving money to buy a regular pci. Any sugestions were I can buy an ati 256mb pci card? Thanks|||Just have that card replaced because there is no adapter.

Consider these:
