Pretty much what the title says but here are some more info.

1. Its not overheating ( 69c on cpu and 45-50c on gpu kinda normal on tropical country imo )

2. It wont power up unless i flip on and off the switch on power supply.

3. It feeling like there was an interval for it when it starts doing that instant turning off and its getting shorter and shorter.

4. Idk if this is notable but it happened 2 time with google chrome being opened and clicking that "restore" tab thing.

For those who gonna suggest i should update my bios idk how will i do it with that instant turning off thingy problem i have rn.

I'll read you reply guys tomorrow. Too tired to do things rn. Thank you!!
