this one thing scared me a lot.
i'm afraid something bad will happen.
there was a humming noise coming out from my PC. it vibrated my table when the humming noise is on.
and suddenly, the humming noise gone. when i opened the left panel, everything seems fine. nothing stopped.
so, what is happening?

additional information:
my PC suddenly becoming slow and restart itself minutes after the sound gone.

ok, i've found the solutions:
1.make sure you plugged the PSU cable properly
2.unplug any unnecesary external devices like ex.HDD, incompatible external hardware,etc
3.if there is an internal storage device that doesn't work anymore, get it out.

that's all. my PC is now healthy :)
