I've had some issues with my pc for some time, and I am kindly requesting for some help. I have a intel core i7 hp laptop. Some weeks ago some keys were not working, and on getting it checked, the issues had magically vanished. However, it has now become impossibile to use it. On booting it up, it automatically goes on air plane mode, most keys don't function correctly, heats up pretty fast, and freezes screen. For example, on google meets meetings, I can only listen, but cannot unmute to talk or anything as the mouse doesn't work on the meeting. CPU states its being overused, reading up to 100%. If you can assist, I'd really appreciate it.
