Thx, but is it possible to overheat within 10 seconds, cuz I can't feel any part of my laptop is hot and even the wind from the fan is cold wind, I am just thinking is it the problem with the hard drive or just the fan, cuz I punch the laptop everytime I lose the game, of course I won't do that anymore, but thx for yr advice.

You might want to tear it down and change the thermal paste. Download hwmonitor and tell us what your temps are.

Turning off fully in 10 seconds would not be from software and is very unlikely it's the hard drive. Those would cause it to hang up during booting not turn off.

Try totally removing the heatsink and applying new heat grease. If that causes the same thing, since you already cleaned out the fan, the motherboard may be bad. I'd also try running it without the battery just to rule out an electronic issue with that.

Sounds like the moterboard will need to be replaced. It's not that hard to break a laptop if it's not taken care of, the case flexes and causes the components inside to flex a bit, including the motherboard and all the little connections to everything else.

I can get to the windows logo and even the the option menu, but no matter which option I chose, it turns off when I was typing my password

you said the fan was noisy so it might be cooling it some but not enough be like running half speed. Does the noise sound like a squeal like the bearing? Like I said mine the fan didnt work at all so it didnt take long for it to heat up it was probably less than 10 seconds

the fan and heatsinks might not be making good contact with the cpu causing it to overheat quickly. Have you tried getting some thermal paste and opening up your pc to look at your cpu? I don't think you can fix this without opening your pc.
