Card not recognised by computer

I have just bought a 16 GB Sandisk Ultra SDHC card (at up to 40 MB/s). I can use it on my old Lenovo PC operating on Vista, but my new Lenovo PC operating on Win  8.1 cannot recogise the memory card.

Is there anything I need to do before the card can be used on my new PC, like downloading some software?


in that case where the card is working fine with another pc you have to see if the pc is working fine in generall

so you have to make sure that the sd slot of the other pc is working fine

that the drivers of the other pc are correctly installed and up to date

if the card reader is working fine with the other pc

so if you know the cause you can find the solution for the correct device that is not working
