How Do I fix a broken SD Card Slot

[lopploio]

On my sister's computer which is a Dell Inspiron 560 it has an SD Card Slot. The SD Card Slot stopped working a while ago and I was trying to help her fix it. The drive letter for it is S: and it says please insert a card. The reader itself is lighting up saying that there is a card in there. If i go into disk management it says the drive is formatted as RAW but it was formatted at fat32. I tried reformatting but that didn't work. The card works in her camcorder and other SD card slots. I also tried multiple cards. Any ideas for a fix or why it could be doing this? Any help would be appreciated.

I would have a check in device manager to see if the device is operating correctly and no caution marks are showing

I checked there and it says this device is functioning properly.
