Card reader not working (Windows 7)

My desktop has a built-in card reader.
However, when I insert a card into the reader it does not appear in Windows, though the reader does light up.

I've attempted to uninstall all of the card devices in the Device Manager, which gave no results.
They reinstall themselves on reboot (or when inserting a card).

I believe the wiring is good because the card reader also features a USB port which does work.

Each of the card devices appears in Disk Management, indicating no media (even when I have a card inserted).

I've only been able to test the SD card reader, as I don't have cards of the other types.

uninstall the device from the device manager and reinstall it with the supplied manufacture software.
Sometimes the generic drivers do not work

I am not quite sure of the exact drivers to use.
DriverGenius indicated that the brand is Alcor, I've tried installing a variety of drivers I find by doing a Google search.
None have seemed to help.

I've tried to update the drivers in the Device Manager, pointing to the Alcor drives, however, it always indicates they are already using the most up to date drivers.

I've never tried the exact method you describe.
Do you mean I should first uninstall all of the generic devices from the Device Manager then install the driver software?

Does the card work in another computer? just because you may have leds that blink does not mean that windows recognizes the device. When you open device manager do you have any items that unknown? or other devices?

The card does work in another computer. I've actually tried several SD cards to no avail.

No unknown devices in Device Manager.
Each of the slots of the card reader show up as "Generic- [Card Type] USB Device" under the Disk drives section.

How old is the machine?  Some older card readers can't manage SD capacities over 2GB (SDHC) however the virtual drives will appear normally in Windows Explorer until a high capacity card is inserted.

As MASQ has already said, it could be that it's an older card reader so isn't able to read a newer SDHC card. It could also be faulty, so try connecting it so another PC to confirm. I personally don't think it would be a driver issue as these things don't generally need a 3rd party driver, the Windows driver is usually the one that is used.

The machine is only a year and a half old. I believe that SDHC cards were supported long before this.
Sorry, my description may have been a little ambiguous, the virtual drives do appear in Windows Explorer, but when inserting a card I see no change.

I suppose I will just have to try it it another computer as many of you have stated.
Looking at the prices of desktop card readers, I may just buy a new one and give that a try and discard the old one if it works.

I bought a new card reader, it works perfectly without drivers.
I inserted the SD card I was testing the old reader with and it appears that the old reader corrupted it (file system and files gone).

All of this seems to point to the old reader being bad.
$25 to gain another USB 3.0 port, a microSD reader, and functionality lost on the previous reader. I'll consider that a win.

I split the points evenly because there was no solution (besides replacing the reader).
Thanks for all of your suggestions and insight.
