Canon EOS 40D - err. 99 while taking photos

\015 I have a problem with my camera - Canon EOS 40D. The camera is relatively new, I bought it in May. Very often, when I take a photo, the LCD displays a massage: " Error 99. Shooting is not possible. Turn the power switch to and again or re-install the battery". Then I follow the instructions, but the problem tends to repeat. What is interesting, my Canon sometimes takes photos and in such a case, it seems everything is all right. I use a lens EF 17 - 40mm L series. I have changed the lense and tried taking photos with other lense, which I borrowed from a friend, but it didn't solvbe the problem. I don't know what to do. In my city there is no authorized Canon service. I heard from one photographer that it might be a problem with the Software installed on my camera. Where can I download software for the camera and how can i upgrade it i my device?Thank you for your help\015

I have a Canon EOS 40D When I switch it on all appears fine. When I take a photo the shutter remains open & all power is lost. I then need to remove & re-install the battery to recover power.

First of all, don't use the flash...it's only good for a short distance. Obviously, you need a fast shutter speed to stop the action.

The shutter speed priority setting on my Canon 40D keeps jumping to a different speed that I haven't set. E.g - set at 200, jumps to 25 when I go to take a photo. I have spoken to Canon regarding the problem and they have suggested that I clear the user settings. This initially solved the problem for all of an hour, but the problem has now started up again. I'll probably be sending it in, as I think it might be a problem with the hardware, just thought I'd check here first. Any suggestio
