Does any one know how I can fix my SD card slot reader?

I have a gateway 4540gz. It used to work, but suddenly, it just does not recognize SD cards anymore. When I put one in, it makes this double/triple chime (ding ding ding) instead the one ding dong. When I check under my computer, its not there. The SD card is fine, its the reader.

I tried installing a driver from the gateway website ( http://support.gateway.com/support/drive… ) and I tried uninstalling it from safe mode and letting it reinstall itself, but nothings didnt worked.

Is my reader broken???? IS there no way to fix this besdies buying a USB sd card reader?

Help please? :/
