turning-on

Gumagana naman yung laptop kahapon lang pero turn-on ko ngayon ayaw na. As you can see po from the video, steady yung light ng charger pag hindi naka plug pero pag pin-lug na biglang nag bblink and hindi nag rerespond ang laptop, walang ilaw na kahit na ano... Lahat naman na ng solution sa...

What to do when pc is not turning on? Already tried some basic steps like cleaning ram's pins, removing gpu and using on board vga and changing psu.
