Have you cleaned the old paste before applying? If it is not the thermal paste then it is the fan. Look in the BIOS the temperatures and rpm. You can let it in BIOS for a while and wait to see if it turns off or not.
Does it turns off? OR
it reboots? OR
It looks like it turns off but you can listen to the hardware been powered on and or the leds?
Yes, sir I cleaned the old paste with alcohol and tissue first before applying a new one. I spread it with the spreader that came with the thermal paste, sir.
I looked into the BIOS and, unfortunately I don't think there's an option where I can see the temperatures and RPM. I did wait on BIOS and, sadly it still turned off itself. I tried listening to the vent, hoping to hear the fan. But, I can't decide yet there's a little sound, but I can't feel any hot air on it.
I did make sure that I don't have any loose cable connections, I reseated everything thrice in a row, it doesn't shut down immediately, in fact it can remain alive until I put my password on the login box, and enter it, after that it completely shuts off.
I almost forgot, that whenever it shuts down there's a clicky-sound that came with it.
Thank you for your effort sir.
