Laptop Freezes

[Eijar]

forgot where it starts but heres the issue:

my laptop, Predator ph317-55, i9-11gen, 3070, 24gb ram
lags when i play game(valo, dota, space engineers, etc)
This runs the games smoothly no problems at all, before this issue happened

i start game, it freezes, around a min or, and i got disconnected in online games,

Temps are good, around 80-90 in cpu, 60-80 in gpu depends on game, fans are not even max, and i custom it to higher rpm for more cooling. My laptop has good space, its positioned in slant 45 degree, so fresh air is good

this only happens when i play, or when brownout here, i pull the hdmi, it lags too

sometime when lag are worse, it restarts the laptop, and sometiumes too it restarts and post no bootable device found
so i check the health of my m.2, its 92  but temps hits 56+ using hdd sentinel
no errors found here

tried the sfc /scannow and no error found


So after all of this, now i reinstall windows in settings, so all starts a fresh

with this, all games run okay, then suddenly it came back again

is this drive failure or motherboard itself?

this laptop is not even 1 year in(around 7 months)

i did repaste the thermal paste, cleaned the fans but still it happens,
