Just found this on the Nikon support website:-

My D5000 does not seem to respond to controls. Can I reset the camera?

In extremely rare instances, unusual characters may appear in the monitor and the camera may stop functioning. In most cases, this phenomenon is caused by a strong external static charge. Turn the camera off, remove and reinsert the battery, taking care to avoid burns, and turn the camera on again, or if you are using an AC adapter (available separately), disconnect and reconnect the adapter and turn the camera on again.
If the problem persists, turn the camera off, open the memory card slot cover, and using a paper clip, gently press the reset button by the memory card slot. ( NOTE: This will also reset the camera clock. Also note that disconnecting the power source or pressing the reset button may result in loss of any data not recorded to the memory card at the time the problem occurred. Data already recorded to the card will not be affected. In the event of continued malfunction, contact your retailer or Nikon-authorized service representative.

Just type D5000 in the search box

Set it on portrait mode in case your subject is standing away.

1. Your computer must have a software (eg: picture viewer) to show you the pictures.
2. When you connect the camera to the computer, the computer should show camera storage as another storeage divice under my computer. if it is not appearing then the camera is not recognized by the computer..

Try the procedures in this tip.

When you set the exposure mode to Manual, you then have to set the shutter speed and aperture yourself. That's the whole point of the manual setting: the camera does none of the work for you.

There has been a Service Advisory issued by Nikon for this problem. The page for full information is below:
