Question edited for clarity. Your memory card is too big and beyond the capabilities of the camera. 512Mb is recommended. Page 34 of the manual http://gdlp01.c-wss.com/gds/8/0900001188/01/PSA540_530CUGad-EN.pdf ..

Consider NOT connecting your camera to your computer.

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. Or you can use any photo cataloging program.

Try another charging cord. The camera charging cords are just as bad as the phone cords. They just go bad quickly.

There is an internal battery that you cannot replace. IT has to be sent into service.

Try Formatting the card.
Someone could have locked it accidently.
