I'm sorry about the issue. Was it working previously?
Is there any error or message?
Do you have windows xp, vista, or 7, or 8, 10?
With the camera powered on and connected to the computer, open Windows Explorer, then do you see the camera's device or camera's drive letter? If yes, can you open it and open the DCIM folder and view pictures and/or transfer?
Please reply at the box below. Thank you,
