There was a class action law suit on the GPU on this model, then a repair program which has since expired.

(see the bottom of the page)

So it is a well known issue. A lot of success has been had using a hot air work station to reflow the GPU. There are also several companies offering repair service of this model on eBay that will attempt repair or replacement of it.

In my opinion a reflow is a temporary fix and dosnt solve the problem, what really needs done is a replacment gpu soldered on as chip is damaged and heat makes it appear fixed in most cases

That Looks like the gpu is either faulty or it is overheating and needs fan claened and probably new thermal paste on gpu
