Try 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). 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 management program such as Picasa ( http://picasa.google.com )

Go to the menu and access your memory card and then reformat, it will then verify that you will lose all pics and just click on yes...then card will be empty.

It's very hard to troubleshoot software problems online, and it likely is a software issue. But why put up with the headaches of bad software in the first place? Please see this article, as it describes the use of a card reader as a much easier, faster, and less error prone way to download your videos and photos.

try using a camera tripod or leaning against something sturdy, like a building or tree, especially when really zoomed in! As the light dims, the camera will choose a slower shutter speed and/or wider aperture (in automatic) to produce a picture that is not too dark. As a result, the camera may take blurry pictures, especially if the camera or subject moves. There is a setting for landscape, which uses a very small aperture, and just about everything from close to far away can be in focus. Hope this helps!

Could be ccd problem. These were common with this type of Canon camera. Download Canon pdf file re these faults.

Two possible solutions.

1. Apple users have reported that the switch on the memory cards performs the file lock function in either extreme positions Lock/Unlock. In some cases they have achieved success in centering the Lock/Unlock switch allowing access to the read/write operation of the memory card

2. Connect to PC
Access drive via windows explorer
Right click on drive (MEMORY CARD)
Select properties
Confirm that RO (Read Only) is not selected.
Selected RO
Try reading card
Repeat properties un-select RO
Try deleting files

If not successful card is likely defective

Hope this helps?

As a solution I highly recommend that you forego the old cable to the camera route, and instead consider a card reader to download your photos to your computer. Card readers are very inexpensive, much much faster downloading photos from the camera, do not use the camera's batteries during download, and are much less prone to file corruption of the photos during the download.

You place the camera's card in the reader, and your computer sees it as a hard drive. You simply copy/paste or drag/drop your photos onto your hard drive. For all of these reasons, most professional photographers utilize card readers exclusively. Really, you'll save yourself a lot of headache. Here are some examples from Amazon. Also, don't be fooled by the cost. some of the cheap ones work just fine. Go by the reviews. Also make sure you get a reader that is stated capable of reading your card (particularly if you have an SDHC card):
