so back in november i got a new laptop hp17-g121wm and everything is fine till recently. sometimes when i'm on the screen will go black but still the back lite is on. i'll have to hit the power button to put it in sleep mode then poser button again to get the display back. sometimes it'll do it right after bring it out of sleep mode and i'll have to put it in sleep mode again.doesn't matter what i'm doing just surfing the internet does it. i checked all the power settings in windows 10 and everything is how it should. updated the video card drives couple days ago and for 2 days it didn't do it till just now. so far it's only after the laptop has been on serveral hours but it doesn't feel hot. any idea what might cause this? processor is amd a10-8700p and video card is r6.
