I recently purchased an Easynote TJ64 laptop from PC world - the model had been "refurbished" giving it better specs. However I cannot get the webcam to work- the screen just remains black when i try to take pictures, or a video. I thought it could be something to do with the upgrade to Windows 7 that the refurbished model contains? Does it need a different driver or something? All my attempts at googling them have failed. I am clueless really! Any help would be much appreciated.
