Question about Nikon D40x Digital Camera
Sounds like you need to get your camera fixed by Nikon.
However, you say the auto focus stopped working, you didn't switch to a lens that uses a mechanical focus linkage do you? The D40 only supports lenses with AF-S or AF-I type autofocus drives. AF-D and AF-G types without AF-S or AF-I don't autofocus.
Also, check that the A/M switch on the lens is in the correct position.
Manual focusing is quite difficult to do accurately with an AF camera. The screen inside the camera is not optimized for this. If you are sure you are focusing accurately but the pictures you take are still out of focus, the mirror may need adjusting. I can provide further info on this if you require, but if you're within warranty, i'd recommend that route first.
