When i insert my sd card in my dell laptop it doesnt read anything why is that?

Hello.... hard time to read sd card into your dell laptoré. or your sd card is burn out or your missing a important driver inside your system configuration.... let check if you don't have any missing driver inside your pc.. first click on setting control panel then hardware and device manager.. see if you don't have any driver is missing ...it showing automatically on the column,, by clicking on-it try to update or re-install sd card drivers this is due to corrupt drivers... but first try another sd card inside your pc see if it work if yes your original sd card is burn out... good luck
