So, I got my laptop on October 2014 and it was running fine until, when i recently started to watch netflix, my laptop screen started to flash black and I realized it starts to flash black for a second, the sound is still going while I stream netflix, it gradually increases the flashing and starts to flicker, when I pause the video, it stops and I realized this happens when I stream videos( youtube etc). Then as I let the flashing happen, the flashing continues even when I am not streaming any videos. It happens until i shut it down for a while and triggers again when I watch approximate 30 minutes into the videos. Can someone help me? My laptop is an Asus Notebook with Intel HD graphics family.Should I roll back my video driver?
