Today i was playing apex legends everythig was fine until my monitor Just went Black and text has shown that says entering power save mode shortly. And when i wait the computer Just restarts and backs up to normal with no problems. I launched the game again and that happened again. The strange thing is i tried other game, same thing, i tried to benchmark with 3dmark demo and when the benchmark started same "entering power save mode shortly" so i tried to unplug the ram clean it and plug it again same thing with gpu. Launching the game playing 1-minutes and boom same thing. Later i tried benchmark and playing like 15-20 minutes i was thinking it fixed but again happened. The temps of The gpu and cpu is normal its not overheating for sure. My specs are
