Hi friends
Firstly i had get this laptop it had graphic problem so i reballed gpu,laptop worked about 2 month and now i get back it with same problem.
I had some internet browsing and i obtained that g86-631-A2 is cooler than G86-635-A2 and they are changeable with each other, so i changed gpu chipset G86-635-A2 with new g86-631-A2 one.Now laptop has no image and sometimes turns off automatically.
Are those chipsets really changeable,and if they are,so should i change system bios ?

I realized that Switching to G86-631-A2 on -> G86-635-A2 is impossible, so i change it with new g86-635-a2 and it is ok now.
