Clutching at straws here but your not running a dual-boot system are you with Ubuntu as a second OS? I ask this because Ubuntu, a Linux distro, uses two clocks and when selecting Windows OS it takes a little while to show the right Windows time. Synchronising the two Linux clocks fixes things.
rdave13 When I start up the computer the Medion sign comes on and it shows the time on the top right of the black screen which is 1hr 5 minutes difference from the Bios and the computer time. Eventually it goes on to the welcome screen.
Not got a clue as to whether it makes any difference to the computer or not. Thats why I am asking the question.
