Hi,

for a second time now, a weird bug has occured on my PC and it's giving me a scare.

I usually don't turn it off, just sleep it, and everything has been fine until very recently. When I woke the PC up after a longer period of sleep, the screen was just blinking black and white vertical lines. I could move a small square with my mouse. Nothing seemed to help, so I restarted it and it was working okay again.

I've recorded a video on my phone that should be much more explanatory: https://www.dropbox.com/s/2efpdjnvkepvc3j/2017-10-21%2016.46.11.mp4?dl=0

I'm running the fall update of Windows 10, CPU is i7 6700K, MSI Z170A Krait MOBO, 16GB of Kingston DDR4 RAM.

Do you have any idea what may cause it? If there's any other info I should provide, please, let me know.
