Guys, I need help with something. It's about my Windows laptop. It's an HP laptop. Right now I'm experiencing a huge problem. When I turn it on and start using it for about three hours, it works fine but after those three hours, my laptop starts acting up. The problem is this: the internet (my internet doesn't have any problems at all) gets very slow, I can't open the start menu (I can only right-click it but I can't left-click it to open) and I can't right-click any app in the toolbar and I can't open Settings nor use it. I restarted it and it goes back to normal but after a while, the problem comes back. Can somebody please help me out here? I m really worried!!!
