Another possibility is that the reader has gone bad, they sometimes do. Go to your device manager and see what the status of the reader is (and if its even listed) I am going to assume you know where to find the device manager.
If there are any non working hardware components they will have either a red X next to them or a yellow! If you didn't get the right drivers this is where it will show it. Click on the flagged items and reinstall the drivers. Then test it. If everything looks good but it is still not working, find the card reader in the device manager and uninstall it.

Reboot and let the system find it an put the drivers back in. If this doesn't fix it or if it doesn't show up at all then the reader is probably bad. To get to the device manager, RIGHT click on my computer and go to properties which is usually at the bottom.
In the system properties box that opens up, click the hardware tab. In the hardware box click the device manager bar/button. The device manager box gives you a list of all the hardware devices in your computer. Click the plus to get to the details of any item.
Usually the card readers are listed in the Universal Serial Bus Controllers as mass storage devices. They can also be listed in the Disk Drives section. 'Generic USB SD Reader USB Device' Right click and go to the properties so you can get the box for that individual device. There is a troubleshooting button.
Under the drives tab you can uninstall the drivers. Remember how to get to this place. The device manager is your basic starting place for hardware problems.
