Usually when I want to transfer photographs from my camera to my PC I simply put my memory card in a card reader and put it in the slot in the PC and then a box appears on my sreen and it works like that. Today tho for some reason no box is appearing. My card reader lights up and I hear the "Ping" which tells me I'm ready, but nothing.
With the computer on and looking in My computer Unplug and reconnect. Nothing? Go to Control panel/desistem device manager Any big yellow gobbets in the USB area? Shut the computer down and restart Connected now? Big yellows? Got device and 'Rollback the driver. Come back tell whats happening - good or bad
