My computer won't show my sd card on the screen

Hello,

the reason your laptop wont show your sd card on the screen is because it is not reading the sd card.

it is not reading the disc either because
1. there may be a problem with the card reader,
2. there may be a problem with the slot on the laptop,
3. there may be a problem with the memory card.

to check if it is the card reader, try to use the same memory card reader with another sd card on another laptop and see if it will read it.

to check if it is the slot on the laptop, try to use a new sd card and a new card reader on the laptop to see if it works, if it does not, then you know where the fault is from.

finally, to test the sd card, try to use it on another laptop to see what happens. if it does not work then you can tell where the fault is from.

whichever the fault is, you can change them.

but if it is the card slot, you will have to open up the laptop and clean the slot carefully.

take care.
