I have been an ongoing issue for the last month, but it has been getting extremely worse over the last couple of weeks. My screen will randomly turn black, usually when playing a game, but a couple of times it did it without been on any browser or game (when I rebooted). The screen will turn black and freeze up, most of the time it will come back but there have been times where it sat in limbo. Also at the bottom of my screen there will be a triangle icon with an exclamation point in it, and it will say sometimes "in power saving mode" although I have already checked and that is not a selected option in my power plan. I am on the new Windows 10. I am so also running a dual monitor one is a Dell S2330MX and one is a Samsung S24B300. I have continually blown dust out to make sure it wasn't overheating. I am so frustrated why this is happening. Please help.
