Foer some reason or other my daughter's computer started showing the wrong date , so I went into Date andTime Properties>>>Date and Time tab and the box for the month showed the numer 7, not the month. When I clicked on the drop down menu it showed a list of twelve 7s and not the actual months .
I thought it might be the battery on the motherboard so I replaced the battery with a new one. No change.
Any ideas please.
