How do I get the memory card and data cable to work in the computer for the LG Xenon?

I have an Sandisk Micro SD 4gb and when I put it in the computer, nothing pops up. So after a while, i go to my disk drives and when I start clicking on stuff, it freezes the computer up. Then I got a data cable, that didnt work either, nothing popped up.
