I have a Gateway laptop running 64 bit windows 7 home premium. My previously working internal card reader has stopped reading cards. I have uninstalled and reinstalled the drivers. The weird thing is that I have tried five different SDHC cards. One Transcend, Sony, PNY, and two SanDisk. For some reason the two SanDisk cards work fine which makes me think it could be a hardware problem. The other cards work fine in other computers and in cameras.
