i try it all, its not the windows\driver becouse even the bios is not readable.
i'm looking for hardware accceleration software or some idea to reset the graphic card.
in other computer it's the same result.
i can start windows normaly when i disable the nvidia card in the device manager, after enabling it back, the windows starts with black screen with green dots, but the voice is working well like other things :O
i solved this issue before by playing with the hadware acceleration, i believe it's something with the card hardware but can fix it by windows, i succeeded last time and now it failed :\
pc technician told me that my gpu get stuck in some infine loop and it's a rare error.
if anyone have a solution for my problem, i will be thankful. sorry for my english
