    On device manager, click on "view" tab and choose "show hidden devices" and look if VGA adapter will appear.

    can you take a screenshot of "display adapters" on device manager?

     

    If not, please check in BIOS if there's any option to enable/disable the GPU.

    i completely formatted harddisk and clean install win 8.1 again.Nothing changes.Gtx 850m shown in hidden devices and there is nothing only boot options in BIOS.I think it is probably a hardware problem Man SadAdsız.jpg

    the error code 45 on Nvidia, means a disconnected device (Currently, this hardware device is not connected to the computer.)

     

    Can you report here your BIOS version?

    You can try but i'm not sure that software will be able to reflash the same version.

     

    i think it's time to contact Acer support service of your region.

    Before flashing the BIOS, i would try a "load default or optimized or Load setup defaults" on BIOS if available, save and exit.
