I bought a Laptop HP Pavilion n033eg with Windows 8. I installed Windows 7 on it and it seems that I got all the drivers as the device manager doesn't show any problems. Later on I detected that the card reader is not working... I insert a sd card and the device manager came up with a problem with a PCI device. It says that no drivers were installed (code28). Everything about this device is unknown and and searched online for drivers without success.
