Last night while I was playing a game, I alt-tabbed out of it to change music. When I tried to get back into it, the screen was just white. I couldn't close it. Opened the task manager but the game was still taking up the whole screen(the game was in fullscreen by the way). After I couldn't do anything, I forcefully shut down the laptop by holding the power button. I did not turn the laptop after that. The next morning, I turn on the laptop, the laptop brand logo shows up and then a blank screen. Usually what would happen, Windows would load and then I would be taken to the login screen but Windows isn't loading at all. Anybody can help?
