Hi. On Optimus Series: 17.3" Matte Full HD LED Widescreen (1920x1080) of 2014 I have reinstaled Win 10 and now the card reader does not appear in file explorer and device manager. In device manager Other devices has a "?" annotation and all sub devices have a yellow triangle so i guess its a driver thing. I have a copy of the driver cd with card reader drivers which came with the pc but unsure how to use it. Please advise.
