Hi friends,
i am repairing this motherboard and i have some strange problem.
The mac after start Unigine Heaven with GPU Nvidia 650M freezes, and logout from the OS.... really only logout from the OS! I must enter the password to the OS and i can continue. The computer does NOT restart or shut down with message GPU panic as is customary. Only freezes and logout. When i start Unigine Heaven with Intel GPU, everything is ok... so, the problem is with only NVIDIA GPU.
I try replaced GPU for a new one and reballing GPU-RAM, replace U8900, but the problem is the same.
Can you anybody help me? Some idea?
Thank you very much.
