Hello, the computer is a Lenovo desktop which runs on windows 8
Sorry for delay. I've taken this info from the rear of the computer.
Machine type: 4773
That is everything I can find. Hope it helps.
Downloaded but photos taken earlier today don't show up. Camera plugged in. Sony Eperia Z3
Sorry about that. I'm also plugging in a camera via USB slot. It was the card reader which also didn't work earlier. So now the camera shows nothing.
