    So I ran a stress test after benchmarking (stress was just running heaven on a loop under 8x ultra extreme). The laptop crashed after about 30 minutes, and when it rebooted the 980 is gone from the system profile, device manager, and anywhere else I've looked. . . Just upgraded to windows 10 prior, any thoughts?

    Yes, definitely... Ah well... at least now you've got telemetry...
    If you have UEFI/Secure Boot/Fast Boot enabled, no telling.
    It wasn't broken, but Windows 10 fixed it for you real good...

    On a somewhat more serious note, can you see the GPU in the BIOS?
    If you have Secure Boot enabled in the BIOS, try disabling it.

    Windows 10 is running fine on my other computer and saw a 5% performance increase. Can downgrade using my windows 8.1 disc if i need to. Using DDU and doing a fresh nvidia instal right now. Next stop will be Alienware support

    Have not checked in bios. Nvidia drivers are installing now. Will reboot and log into bios to check.

    Wow. Nope. It is gone from bios as well. Nvidia drivers failed to even start the installation process.

    Try reflashing the original vbios. Hopefully that works otherwise maybe that stress testing killed the gpu.

    Or the windows 10 killed it. The drivers were 353.2

    How weird. Maybe try a power reset (disconnect AC and battery, hold down power button 30 seconds) and see if it reappears. Also, try resetting BIOS defaults (press F9 in the BIOS).

    Were the temps high when it happened? Maybe some strange thermal protection routine disabled it or something crazy like that.

    You cannot flash the vBIOS unless the GPU is visible. It's not likely a stress test killed it, especially the type of benchmark that was being used for the stress test. It's not that much stress even for 30 minutes. Unigine Heaven is no more stressful than some of the most demanding games. There may have been some weak component that gave out, like a capacitor or something of that nature, but even that is not very likely. GPUs, SSDs and hard drives can sometimes mysteriously disappear with Secure Boot enabled.

    That's not likely. So far Windows 10 has only killed LCD panels on Alienware machines. I doubt it hurt the GPU. Is Secure Boot enabled in the BIOS? If it is, shut it off and see if it comes back.

    Thank you very much, Mr Fox!

    The error i encounter is "bios reading not supported on this device" will disabling the gpu via device manager solve it? i ask this because its not the error you mentioned in the video.

    EDIT: I got it to work when i tried it again it prompted me if i wanted to disable the gpu temporarily.
