Unplug anything you have plugged in to the USB ports and try replacing the internal battery. The USB ports can only deliver a certain amount of electric power - it's enough to energise a memory stick but not all USB keyboards and mice are equal...

 

If the internal battery is flat then the onboard memory corrupts and that can also cause startup issues - the battery is a CR2032 available almost anywhere nowadays and you only need a pozidrive crosshead screwdriver to open the case.

 

Turn the desk over on something soft - undo the screws running along the top edge and bottom edge then gently lift the case up - you'll see the mainboard in the bottom of the case and the battery will look like the new one you bought. Be careful when remove the old battery - too rough and you'll break the retaining clip for the cell. All told - should take about 15 minutes.
