HP 2230s powering off randomly

[lord]

Hi all,
I have this HP laptop it is a 13" 2230s, and it just powers off randomly. Sometimes before booting, sometime in windows.
I cleaned the vent and cooler, checked the cooler, so it's not overheating. My guess is cold joint but i try ti twist the board but couldn't find any pattern of behavior. Also check through magnifying glass for visible damage or cold joints, none found.

Does anybody have some kind of idea?

Did anybody had a similar case or an idea? Because im out of ideas, only to reflow the whole board. But that's the last resort i want to use.

Long shot - have you tried removing cleaning and replacing the ram.
(If it is removable)
