Hello JJ-DK,
Welcome to the HP Forums! I hope you enjoy your experience!
I understand your new computer is experiencing card reader issues. I will do my best to assist you, but first I require the following information:
1. The computer's model number. If you require assistance locating this information, please reference this website: Locating the Model Number of the Computer
2. The computer's operating system. If you require assistance locating this information, please reference this website to determine your Windows operating system.
Thank you for choosing the HP Forums. Have a great day!
