[AsusRogstrix 16 RTX4090!]

My relatively newer laptop (under an year), crashes

have started crashing, n restart sudden, without proper shutdown. Just like that..
checked EVENT Viewer, it says some events of critical, Kernal power "EVENT Id: 41"

First happened once in Oct, Then nothing. so i ignored. but then recently, 6 more times, in last 12 days.
maybe coz i hav started using laptop more recently. & i dnt know if its some recent update..or what.
not gaming much, but heavy browser use, tonnes of tabs open mostly.
Mostly happened, when i m not onscreen.
I am loosing my work, often, kindly help someone..
my system restore points..dont go back more than 10 days.
so i dont know, whats causing that...plz help, thank you : )
