Built a gaming PC back in 2018 (windows 10, GTX1080, i7, eset security).

For the past year or so it wakes up every now and then and for a few months it started waking up to my logged in desktop screen. Hasnt happened for about a month or so but it still eakes up even with my mouse and keyboard disconnected. I don't do any tormenting or anything sketchy. It's a really clean machine built for gaming, YouTube, office work stuff. I don't visit any "low brow" sites (that's what my tablet (not connected to the PC) is for). It didn't start happening after any specific download that I can remember.

Anyway, I can't find anything relevant online that helps me so I figured I'd ask here if anyone knows what this is about.
