Gaming laptop stuttering/ freezing

Hello, I have an Omen gaming laptop. Intel Core processor, Nvidia GeForce RTX. I bought it two years ago and have been treating it very well, no suspicious downloads, no nothing.

Recently though I've noticed some bad stuttering. Like when I try to scroll, or load a new page, it freezes for a second before catching up with the action I had taken. Even as I type this, sometimes the screen freezes and then a few seconds later the letters pop up.

When I try to play video games the issue is even worse. Literally every 10 or so seconds the game lags and freezes for a second or two, it's impossible to play any games right now.

This issue only popped up this past week, and at first I could solve the issue by restarting my laptop, but now that doesn't fix it anymore. The laptop starts up fine, runs pretty quickly, no long loading times, it's up to date and no new updates are available. My storage isn't even close to full. Idk what could be causing this.

Usually the freezing isn't that bad if I'm just on google/ youtube or something. But if I've got an app like Discord or a game running in the background, the freezing becomes awful when I try to type something or open a new tab.
