BE SURE THIS IS NOT TURNED ON or you can get the effect you noted.
So as I mentioned in the title, my Windows 7 Samsung np-qx411-w02ub laptop crashes whenever I install new display/video drivers. I went to the official Samsung website, searched for my laptop, and downloaded the display driver that it recommended for that model. Whenever I install it, it works fine for about half an hour, but then all of a sudden the screen goes black and some thin, colored lines start flickering on the left side of the screen. After that, I uninstalled the driver, then downloaded another display driver. I installed it, worked good for about half an hour, then the same thing happened. (The standard VGA display driver that came on the laptop works fine, but I would just prefer better display drivers because the VGA one has low resolution.)
Thanks in advance for the help
