    Hello,

    I have been using the latest macbook pro 13.3" since April 2010.

    Over the last week the monitor suddenly goes completely white and the external monitor goes black. The laptop becomes unresponsive although the programmes opened continue running (e.g a skype voice call would continue without interruption although the monitor is all white).

    The only solution at the moment is to press the turn off button for a few seconds then switch the laptop on again. It will then work normally until for no apparent reason this happens again.


    Has anyone experienced a similar problem before? Any idea what could be the problem?

    This sounds like a overheating issue with the graphics chipset.

    Be certain that you have all of the latest MacBook EFI and SMC updates installed ( http://support.apple.com/kb/ht1237 ) , and if you do, you may want to check out a program called smcFanControl ( http://www.conscius.de/smcfancontrol_2_2_2.zip ) It will let you see your systems temperature and increase the fan speed if its overheating.

    You may want to take your MacBook to Apple and see if they can diagnose the issue. The fans can be cleaned if needed or replaced. I'd try blowing out the notebook with it turned off using compressed air.
