Screen goes blank when I plug camera into computer

Probably not...sounds like you did about all you can do.

Try NOT using the USB connection.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program.

Try using a separate card reader instead of the camera.

If, after viewing the pics on a computer, you don't use the "safely remove hardware" function before pulling out the cord/card, the files on the card may become corrupted and not recognized by the camera anymore.

Use a card reader to download your pics.

Install proper driver before making a connection.

Since your two cameras have the same problem with the same computer, I would like to suggest you to connect those cameras to another computer. It looks like the problem is on the computer side.

ugh this happened to me too :( it sucks cuz i have had great pictures i wanted to upload but they wont upload :(
