ok, the tittle already shown my problem. this computer just clean up by myself, what i do is just clean the heatsink and apply new thermal heat compund, and i always do this and its part of my job.
direct to the point, i turn on the cpu and in random time it will shutdown,i already check the psu and try it with another psu giving me the same result.it just doing that random, like when i press the power button and not even 1second last long, sometimes 5 minutes,depend on my luck
It could be loose cable, but even without touching or doing anything to the computer it still shutting down random.the fans is working.
oh, and i didn't try the computer before im cleaning it.That's make it a bit difficult.
any comment will be much appreciate.
