Well if the inbuilt card reader does not recognize the SD/MMC card then we need to perform certain troubleshooting steps which are as follows:
1>click on start
2>In start search box type DEVMGMT.MSC
3>As soon as the device manager window opens up locate an option which reads as UNIVERSAL SERIAL BUS CONTROLLERS
4>There would be a + sign next to the same, click on it and then try locate a driver which reads as REALTEK SD CARD READER driver or JMB38X MS SD SD/MMC xD Card Reader Driver.
5>Right click on that driver and then click on uninstall
6>Locate a tab which reads as ACTIONS at the top, click on it and then click on then click on SCAN for HARDWARE CHANGES.
7>try installing this driver:
