    I have a Clevo P770zm
    I flash the bios of my gpu gtx 970m
    I tried an oc 200mhz 400 mem
    And in furmark black screen and the fans speed max, capslock numlock bling and 22 beeps and shut down
    If I get a new gtx 980m will it start booting?

    I had the same problem, and it was the video card.

    Have you tried an external monitor or TV to see if you get any display through VGA / HDMI?

    Beeps and Fans usually indicate a BIOS error of some sort. Whether it's the GPU or some other underlying issue. Replacing the GPU might solve it but before the GPU is engaged the CPU provides video output for BIOS level instructions.

    Not sure how they can diagnose it as a MOBO issue w/o placing another GPU into the chassis.

    No video on internal/external displays puts the GPU in the crosshairs for replacement.

    Well to be fair if your CPU VRM is dead then you'll get no picture as well.

    Yeah, but if your VRM's are popped then it wouldn't make beeps it would just sit there when the power is pushed.

    This thing happend after a gpu bios flash and a furmark test...
    In my opinion...corect me if I am wrong
    The laptop tries to start but he is trying to use the gtx 970m witch the bios or the gpu is dead, and can not switch by his own on the internal gpu from the cpu...
