Sorry Furax88 but I for one cannot suggest anything else 

 

Testing notebook circuits is a time consuming task that requires specialist equipment and knowledge and so it is most difficult knowing and explaining what and how the MB should be tested without having the board in front of us.

Thankyou anyway...I was hoping in someone else with a similar problem which maybe solved someway.
At this point maybe the best thing to do is a reflow.

You are welcome, sorry that we could not resolve the issue but you never know someone who has resolved the same issue may read your thread and post.

 

A reflow is something that resolves certain issues such as a bad integrated video chip, I can't advise for or against if you are set on it but if it fixes the problem you have done well.

I tried to heat the gpu using a common hairdryier and now the laptop works without errors, but it just works for few minutes due to overheating because the fan stops just a second after the laptop starts.
The fan speed raises only when the temperature is too high and its too late to cool down the cpu; I tried to check with speedfan and it results that the fan speed is 0.
I even tried to remove the fan and connecting it to an external source of power and it seems working...whill that exclude that the problem is in the fan? Any other suggestion to localize where the problem is?
