Sata Card

[don]

Ive got no slots on my motherboard to put my via 6421 sata acrd, so shall i just remove one of the satta card already on my pc motherboard?

well you will need a pci slot for the card.
i dont know what other pci cards you have installed.
if there is something you are not using then just take that one out.

CoFree is right. you will need a PCI slot to put the card into. But without knowing what you have already, we can't make a good recommendation on which one to take out, but that you can take something out and put the sata card in temporarily, or maybe permanently. Make sure not to take out something that the PC will need to run though.
