    Unhappy [Win10v1703Build15063 x64] Black Screen and DPC Problems

    Hello, Lately I've been having an issue where the Display will go black but the system is still on and fine, It doesn't go fully complete black like its off and It's entirely random but it seems to have more chance of happening if the brightness is up to 100. It's annoying because the only method I have to dealing with this is to either Windows Key + F7 to toggle the display off or shutting down the brightness to 0.

    I have no idea why or how it's doing this but I've also noticed my latency and DPC is high despite it causing no more problems after I updated my sound driver (Used to do the whole static, buzzing or outright lag jump sometimes). I'm just wondering if the two may be connected since I'm not well versed in this as others.

    It should be noted the laptop has windows 7 by default but I use a windows 10 disc I created before I restored to factory default settings to fix the issue. And this all started after I used a third party *automatic* driver updater to update drivers that went horribly wrong and no doubt made updates for drivers not customized for this specific laptop and forced me to uninstall most drivers. But as far as I can tell this issue only started emerging a few weeks ago and despite a restore to factory default settings now persists here too.

    It could also be a failing Black-light but I wouldn't think under these circumstances it would have this type of behavior.

    Things I've Tried:
    Uninstalling the drivers (works for a couple of hours before going straight back to 0)
    Update Bios

    DxDiag: Dxdiag - Pastebin.com

    And Finally Latencymons insight

    Since this issue started occurring after a period of time, and since a factory reset did not help, I would suspect a hardware issue. It's possible the connection between your display and motherboard is failing. This can be due to a wire that has a break in it that sometimes results in a short, or it can be due to the connector becoming loose between the motherboard and cable. It could also be dust interfering with the connection. See first if cleaning the system of dust has any effect:

    Hi SirDrone (and writhziden).

    Dxdiag shows G550JK.203, whereas your laptop webpage says there's BIOS 205 2014/11/05 (read the manual for how to update the bios).
    Did you install Version V1.0.0039 of ATK (see your laptop support webpage)?
    By chance, are you using a ps/2 external keyboard or mouse?
