Hello, first of all sorry for my english, but I couldn't find anything that could help me in forums. So I'm having massive problem recently. More and more games are freezlaging on on my computer. I'm afraid it's hardware. For example nba 2k16(now 2k17 too) starts freezlaging when its menu loads. I tried a lot of things. Updated my bios, changed hdd level to FEh, my power settings are the same for pluged in and for battery. I tried to remove battery and it short of fixed.. until I started a game and computer shut down on it's loading process. I've noticed that on other power settings who has different screen brightness for pluged in and battery modes, screen sometimes gets darker and brightens again. That means computer goes back and forth from ac power to battery. Yeah? but as I meantioned, if battery is removed then computer shuts down only when I'm trying to play a game or smth. By the way, my current os is windows 7, but I had the same issue on 8 and 10. Although I've had nice gaming experience for about 1.5 years before this started to happening.
