the power switch of my CPU doesn't function. Just a spark then it turns off. Can't identify what's the problem yet. Guys, I need you help on this one. thanks - tagz017

Does your PSU (power supply) start to make a noise, or does it not do anything when you press the power button?
Also check that all of your cables inside of your machine are connected where they should be. One may have come loose and so your computer doesn't boot. Also check that the cable that connects from your switch down to the motherboard hasn't been knocked out of place, which would also result in your computer not starting.

it exploded yesterday :twisted: i have to change its power supply

woah! Why did it explode? And what exactly exploded? Did you put the positive in the negative?!?
