That's kinda like a rolling stop instead of actually stopping. Removing the cpu and all components is the idea, not just some of them.
well, as i said before : i had just the power source and the motherboard , so no cpu , no gpuy nothing just the MB and the psu; btw it did the same with all the components installed
tank you rfor your answer thou
BTW thePSU is OK , i've tested on a different computer and it works fine
