Try this site for card reader drivers.

All I can suggest is you try different ones from the driver download section in the hope you find a driver for your card reader.

Your other option, of course, is to connect your device (I assume it's a digital camera?) to your computer with its USB cable and transfer the data that way.

dear any type of flash drive or card reader is not working in windows 7 .
but they work in my windows xp .

Obviously the card is incompatible with Windows 7.

You can either connect your camera to your computer to transfer the images or use XP Mode
under a virtual PC.

Windows XP Mode - Install and Setup

It sounds like you didn't load the chipset and/or USB drivers for your motherboard.

Also check whether USB is enabled in the BIOS.
