Lately when I plug in my digital camera my compurns off. This hasn't happened before so what's going on?

It isn't the USB port because I plugged in the cable first and it was fine but it was when i plugged the other part into the digital that it turns off. It doesn't matter which port I use either.

You might have a conflicted driver. You might want to check the camera's manufacture for updated drivers. I would recommend purchasing a card reader to transfer you photos to your computer.
