Hi, im a realtive novice when it comes to conputers, i usually just use my laptop to run a few client games and some steam applications, nothing heavy. After attempting to alt tab out of a full screen application, my laptop seemingly crashed. After rebooting the laptop the led power indicator turned on, the fan was audibly running, but the screen displayed nothing. I tried connecting it to a separate monitor like my friend told me through an hdmi cable but that did not work, as the monitor read no signal. I pressed Fn and F5 afterwards and that turned on the screen on both the laptop and the seperate monitor, and it worked fine, but when i logged on to windows (10, not updated in maybe a month and a half) the screen went white. I could alt tab and my previous windows i had open showed up, but when scrolling though it would not shift to any of the windows. From there i force shutdown my laptop and now its back at square one. Any help?
