Laptop not detecting SDHC card anymore

Okay, I'm not sure if this is where it goes, and if not, I apologize.

I have a Gateway NV54 laptop running Windows 7 64bit premium. It has a multi-card reader on the side, and for over 2 years now I been using it to transfer pictures from the SD Card I use in my camera to my computer because I don't have the data cable that most cameras come with.

It (the memory card) was working perfectly until wednesday. That was the last day I used it. It still works in my camera (i just took a pic a few mins ago), but my laptop is not reading it or even detecting it at all anymore. I tried rebooting my computer, taking it out and putting it back in the slot a few times, and nothing. This past wednesday, I did use a sd card from my brother's computer to transfer pics, but I've used other cards, including micro sd cards and never had an issue.

My device manager shows the built in reader is working, so I can't figure out what the problem is to even try to fix it. Can anyone help ?

  1. Could be a dud card or a dud card reader.

    Try another sd card.

    Try your sd card in another computer say via a usb card reader.
