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.

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: How to Clean the Dust Out of Your Laptop
