Welcome to the HP forum!!

I grasp that you have only had the notebook for about 1 month and you are experiencing a difficulty with the card reader.
Here is a document to assist you with that. Using and Troubleshooting Memory Card Readers (Windows 8)
If you would like further assistance would you provide the exact model of computer you have and the operating system. How Do I Find My Model Number or Product Number?
