it might be a problem with the battery connectors.
They might not touch the battery well.
another reason, it might be the battery is dead or the power button is not working.

It does come with software but if you are running XP it should pick up the camera when you put it in play mode and load the generic drivers for it after it loads the drivers check in my computer to see if their is a diffrent drive letter.

hi

the 400d has a sensor just below the optical view finder
it detects when you face is near the view finder and turns off the lcd scren

the display button (top left) can manually turn the lcd on/off

refer page 101 of the manual to modify this setting

You can download the user manual here:

you will have to 'Play in Depth' with the help on the manual here to establish what it is you are doing that the camera not like. For example if in load light conditions and you have set the camera to manual, then it could block if the manual setting does not suit the light condition prevailing. So manual out and a good read through
