So, I was on youtube not really doing anything, just the regular stuff I normally always do, but then the audio started to glitch and when I tried to move my cursor the display feezed and then the cursor was moving in like 1 fps per 3 seconds, it was horrible. I tried to open the task manager to see if some application is taking like all my RAM or something like that, but the PC was so glitchy I had to restart it. So I wanna ask what the hell happened? I need to know what this was, if I should worry, if I should clean my PC or anything else. Thanks for any help.
