its like instanstaneously. it all started one day while i was watching something and it just froze. then i did a hard reset and this problem appeared ever since
 
What you have, maybe, is a component on the motherboard is defective, this is the reason the laptop shuts down after around 3 seconds. Which component is defective, the only way is testing how the laptop is powering up, will reveal the bad part.

so how could i test that?
could it be my hard drive? i really doubt that though.
 


Yes it will be a wise choice, because troubleshooting the motherboard, you need experience and the knowledge of how the laptop is powering up. The best way to resolve your problem, if you don't want to go to a store for the repair, is to buy a new motherboard, it's cheaper than the repair.
