I own a Vaio VGN-SZ38GP which came with two gfx cards, nVidia and Intel. Display is regulated through the stamina-speed switch present on the laptop. Stamina switch is for Intel gfx and speed switch is for nVidia gfx.
The switch started malfunctioning some time back and now the system is stuck with intel gfx. I did a lot of research, Q&A over the internet but couldn't find any solution. Some guy also refereed that the GPU is dead!!!!
The device doesn't show-up on the device manager. Installing of nVidia drivers shows an error "Failed to update driver". Is the GPU really dead? Please advice.
