1.power supply might be faulty
2.motherboard is damaged
swap the power supply if nothing works take it for service

note in new systems it is normal to experience a the CPU fan stopping for 2-3 seconds and then powering on fine when power button is pushed
i had experienced the same problem swapped out the power supply and i was good to go

thanks for the feed back. i already change new power supply because previous power supply is fault. After the replacement, CPU fan stopping for 2-3 seconds if i push power button. but if i press and hold it, CPU fan running great.

best thing to do is take it to a service center near you if you have warranty take it there so they can replace if something is bad.
it is possible that the mother board is damaged due to a power surge and mess up the circuitry that powers up the fan.

It looks like a short, but it might be a faulty motherboard also.
Try taking the board outside the case, install only CPU and CPU fan and start the board. See if spinning without holding the power button.
If wires not long enough, use a screwdriver and shortly touch the 2 pins on the motherboard corresponding to the power button.

if the warranty seal was on the case tell them it was dusty inside and i blew it with compressed air and i had to open the case.
if you removed stickers from the motherboard nothing to do there.
every component has its own warranty motherboard may have warranty 2 years gpu 4 years.
