Sandisk SD CARD

Hey all, Im new to this forum. I have been having trouble putting information on my SD card. Its a microcard with a transflash adapter so I can use it in my Inspiron 9300. When I put it in, the computer recognizes it and can read it. But once I go to drag anything on to the card (I also tried useing Winamp) I get a blue screen, and the blue screen actually doesnt even load all the text. I tried reinstalling the driver and everything. Anyone have any ideas? I can use it fine on my girlfriends HP...... grrrrrr. Thanks guys and gals!
