Unknown Problems

Hello. I come to this forum to see if anyone has a solution to my problem. I got done playing a round in a game, and the game froze. It's never done that before. I tried to exit out of the window, and my computer wouldn't close it. I then had to restart my computer, and upon doing that I closed out of everything and ran a scan with Malwarebytes. It found a malware in the discord localappdata, and it wouldn't complete the scan. I tried to open up task manager, and it opened but wouldn't respond. I tried to ctrl + alt + delete to restart my computer, but it didn't restart so again I was forced to shut it down with the power button. So here I am, with a task manager that won't open, a file explorer that takes forever to open, if it even does, and a laptop that will only restart a very little amount of times. I can't find solutions to these problems on the internet anywhere, so I came here. And I did delete discord, and it won't re-download. Not to mention that Malwarebytes scanned again and came up empty. Even pressing windows + X to open up file explorer or task manager won't work. But my Google Chrome works just fine, seeing as I'm posting this. I can use Chrome just fine, and probably most other things, besides task manager, file explorer, or restarting/shutting down my computer without need to hold down the power button.
