PC not seeing micro SD in adapters

Hi, I've got a problem with my Kingston microSD card or my PC but i don't know which it is. When I insert the mircoSD in via the USB adapter OR the SD adapter it's not recognized by my computer, nothing pops up/no new device is recognized. However, the card still works perfectly fine in my NDS lite. Can someone please help me?? Any advice would be greatly appreciated!

If you have any other microSD cards, then try connecting those to the computer. If it doesn't work, then try another USB port. If that doesn't work, I think it's the fault of your computer.

Does the drive letter show up in my computer when it's plugged in?

Nope, there no new drive displayed in My Computer or Windows Explorer. Unfortunately I don't have any other micro SD cards to test with. It was working fine for about 3 months but just suddenly wasn't recognized.

Do other USB devices work in the same port?

Yes, my USB drives are all working fine, and I've tested the card reader in all of them as well (which still don't work for the microSD)

your card reader may be broken then. Try it on another machine if you can (preferably one it's not been used on before)

Thanks, I will. I hope it's the reader, it'll be so much easier to replace.
