I have windows 10 on my new system and when I insert my SD card it wont show its content. I plugged my camera directly into the computer and still not showing up. I go into windows manager and I can see my SD card in there but when I right click I cannot assign a drive letter. Everything is greyed out. My USB flash drives are all showing up and all additional hard drives. The SD cards I saw are FAT32 format from the camera. When I put them in my laptop and another desktop the pictures show up> any suggestions please as this was suppose to be the replacement for my old desktop.
