Re: lenovo G470

there is a (PCH) chip on board

Re: lenovo G470

PCH, i doubt it. if its a video problem could be it, but it seems to me data transfer problem..

Re: lenovo G470

Have you tried using a different power adapter? I experience this in some laptops I fix. Adapter gives correct voltage but cannot handle load when plugged in. When I place my ear very close to the charger I can hear sparks inside.

And also check the system log on the event viewer on your computer management properties and see if it reports something regarding the processor being underclocked and if it does processor might not be getting enough power. Try it hope this helps. ciao!
