Screen freezes and begins to brighten, sound continues

so i just signed up to ask for help with this problem as i couldn't find anyone having the same issue.

---

the problem?: the screen occasionally freezes (all movement on it stops but sound continues like there's no freeze), after freezing the screen starts getting brighter and brighter until eventually (after a few minutes) it becomes completely white. at that point i can press the power button to send the laptop to sleep mode and open it again in a few minutes (at times, i open it and everything is back to normal) or long press the power button and force a shutdown.

when does it occur?: it seems to happen most often while im playing games although it has happened at complete random too.

solutions ive tried (and did not work): -sfc / scannow, -antivirus scan (both win defender and other apps), -driver updates, -system updates, -throughout sift through startups and processes(autoruns, procexp), -reliability history (nothing suspicious found)

does anyone have an idea how to stop this from happening?

hopefully ive posted this in the right section and understand where the system specs that i provided on signup are.
