thank you for all replies to my question?

Question

i have 3 spare pci slots but the slots on the pci do not match up to the ati radeonx 300se board thanks for any help

Answer 1

It is probably an AGP card, not a PCI.

Or... You might try turning it over =)

Answer 2

That's because you're trying to put a PCI-E video card into a PCI slot. The reason they sound different, is because they are. You need to take the card back, and buy a PCI version, like these: http://www.newegg.com/Product/ProductList.asp?Category=38&N=2010380048+1069609642+1305520549+106790809&Submit=ENE&SubCategory=48
