Sdhc card is not recognised by computer! ? - sdhc drivers

Hello, I bought a 4gig SDHC (Micro SD High Capacity), but when I was in my card reader my computer says computer then plug the card! I also tried a card reader the same fate. I tried updating the drivers on my computer, but in vain. What can I do? I have a dell m 1710th Do you know how I can recover data from one computer to SDHC. I have Windows Vista Home Premium. Thank you!
