I have a Benq R56 laptop, 1GB ram, 1.5GHz cpu, 8400M g gpu and I have Windows 7 installed on it. Everything is running perfectly, except one thing, webcam, sometimes, Webcam Companion 2, program that came with the laptop, detects the webcam but displays only black screen and sometimes it doesnt and says "Web Camera is not connected or is being used". Webcam name is QEye and its built it so I dont understand how it cannot be detected... The weird thing is, it worked before, because, when I installed windows, I went to check does it work, it worked, and today, I was about to start a video call when I realised its not being detected! I tried updating drivers, reinstalling them, rebooting and running in safe mode, nothing helped. Please help! Can anyone help me?
