Accer aspire d255 whitescreen...

Hello,

i have here an accer aspire laptop who's problem is whtescreen after a minutes. whitescreen varies depending upon the usage, sometimes when the laptop in standby mode it takes an hour before it got white but when i use it in gaming even movies it takes only a couple of minutes.

i turned off the unit and turned on again, the program cannot properly load because it white again... same result when you turn off and then on.. it needs a full turn off of 24 hours or more to use again..but same result when in use when movie.. but as i observed that i connected a pc monitor, the laptop screen is white but the pc monitor is still a good display. i can use it through the monitor..

any ideas are much warm welcome...
