Windows 10: Laptop is really choppy all of a sudden

I started up my laptop just like any other day to play a game called VALORANT. I could already feel the fps was really choppy on my home screen, mouse felt draggy and whenever I pressed the windows button or opened up a new tab. Never thought of it much but when I opened up my game, it became REALLY choppy. I restarted my laptop several times and made sure it's on the latest windows update, but it starts lagging from the get-go.

Choppy video, all sources, 2 different PCs (long post)


The video problem persists. My ISP sent a new modem, but it made no difference on streaming video, so the problem must be somewhere in the computer. I just can't figure where. This is driving me crazy, because I can't watch any video on either computer because the choppy playback is too distracting.

I thought for a moment that the problem may be with the SATA driver or controller, as my Device Manager shows only the following, and if I'm not mistaken I'm supposed to see channels listed as well.





But I just checked a video I recorded on my standalone recorder on a USB 3.0 flash drive, and it's choppy, too.

Doesn't anyone have any suggestions?
