Thanks for getting back to me. I have tried what you suggested, and I have tried the function keys. The machine is one month old and the people we purchased it off are now no longer in business. With what you suggested it just turns the screen around, rotating. The problem we have is the screen is mirror reverse where its like looking at it back to front (inside out) like we are looking at it from the inside of the machine. We just cant work out how to change it.
What happened was my daughter was downloading a game and went out leaving the notebook on to finish downloading. When the came back the screensaver was on so they moved to mouse to get back to the screen and this was how they found it. We have done the virus scan with Nod 32 and Combofix and nothing has changed shown there was a virus.
Any suggestion greatly appreciated.
