So my acer aspire 3 a315-42-r4aa model laptop just arrived. Everything seemed fine, downloaded windows and everything was good. When it was like half an hour after i turned it on it just turned off. No warnings, no shutdown screen, nothing. Just a black screen. I turned it on again and after an hour it did it again. Timings were completely random, no indicators, no strange sound, no performance issue. It just boots off for no reason. It is not getting hot, my fans are working and idk what could be causing it. Can anyone help me diagnose it?
