SD card reader not working!!!

When I upgraded my Vista to Windows 7 I had to reload a lot of my drivers, now my computer is not reading my SanDisk Memory StickPRO Duo with my pictures when I insert it into the SD card reader.  It used to be just plug and play.  Now it's not even recognizing it - nothing happens.  I have a SONY Vaio Laptop VGN-CS190.  Please Help! -



1.      Check if the device is getting detected in device manager. Follow the steps to go to device manager

i.                    Click Start, type devmgmt.msc and press enter.

ii.                  Search for the name of the device


If the device is not getting detected in device manager, then check if it is hidden device.

i.                    Click show hidden devices under View

ii.                  expand all the nods under device manager

iii.                There would be many grayed out entries in device manager uninstall all the grayed out entries under all the nods and then restart the computer and plug the external device to the computer and check if it works


2.      Install the latest drivers from the manufacturer website and even make sure the driver is compatible with the version of operating system installed on your computer. check if it works



Install the driver in Compatibility mode:


3.      Check with any other another SD card if it is getting recognized or detected or you may even check if the same SD card is getting recognized or detected on other computer
