Digital camera won't take a charge [View all]

The battery shaped icon is red and just blinks, so I think it's not charging. Would a new battery fix the problem?

Also, I bought a used computer from a local computer guy. It would not read the SD card from my game cams. It did not even show that a drive was being used. I brought it back and he agreed the reader is not working. He gave me a separate scandisk reader. I plug it in and it lights up. I put in the SD card and that lights up. My computer makes some noises, but I don't see any indication of where the pics are going. I click on "my pc" and it does not show any external drives.

Thanks in advance for any suggestions.
