In reply to Robert Durran:
drivers... little bits of software that make each "device" attached to your computer to be recognised and understood by the operating system. windows can sometimes take a few minutes the first time you plug something in to install the driver.
when you plug the camera in and switch it on, does the laptop make any kind of noise or does a new icon appear next to the clock?
unless your gear is really old or really new i'd be surprised if win7 doesn't recognise it... what sort of card reader are you plugging in (single slot... multi slot) does the laptop have a SD card reader built in? does it recognise cards plugged into that?
