    Ok thanks, the intel integrated HD 530 graphics is giving a black screen when the driver is install so I'm hoping a bios update will fix it as I've tried other thing without success. :)

    Also, Do I just flash the latest BIOS 1.05.07, or the latest BIOS and then EC 1.05.05? Also, How do I do a backup of the current BIOS on a clevo? I've only done Alienware. And, would there be any difference from the stock bios than the Metabox bios?

    Depends! You should contact Metabox and get them to send you a BIOS modified by them!

    Shoot Metabox an email and they'll sort out the new BIOS for you.

    That being said..
    If you're booting to a black screen on Intel GPU you may have a corrupted display EDID. I had this issue occur on my P650RP6-G. Notably, I "lost" G-Sync when this happened.
    The Intel GPU simply fails to display when a corrupt EDID is used. The Nvidia driver is more reasonable and just loads a default one. My rig would also get Code43 errors on the GPU when using a driver newer than 388.75 (older worked).

    That particular generation of motherboards shipped with read/write enabled on the display EDID for some insane reason. This also affected many Dell/Alienware machines and was commonly triggered by using EVGA Precision X1 which would accidentally write garbage data into the EDID.
    I had never used EVGA Precision, but the EDID is accessible over a very low voltage I2C bus so it's very possible it was corrupted due to static.

    Fortunately for me, I had a copy of the working EDID and could flash the corrupted parts back over via Linux and an external monitor.

    If you have this particular problem shoot me a PM.

    I also would not be surprised if a large number of these Pascal boards of the same generation that had Code43 GPU errors (VERY common) were actually just in this dead EDID state and ended up getting RMA'd.
