yesterday i finally got all the parts need to put together my new comp. i installed everything into the case properly and was about to power on for the first time, but... nothing.

when i flicked the power switch, nothing happened. no fans, no lights, no nothing.

i then unplugged everything from the power supply to see if that was the problem, and powered it on, but the PS fan didnt spin.

would that mean that the powersupply is defective, and i need a new one? or is it some other issue? thanks guys.

most power supplies will not work (spin fan) without being hooked up to anything.

Did you correctly hook up the power switch jumper cable to the motherboard? I don't think anything will happen if that's not hooked up.

look in your motherboard manual.... look for "cmos setting" or somthing like that.. motherboards come shipped by default with it on "clear CMOS" and with that set your box won't turn on.. put it on "normal operation" that is just another jumper setting..

Like AdmStng said, make sure that the clear CMOS jumper is set right.

After that, just plug the PS into the motherboard and only connect the power supply button cable and see if it powers on. If it doesn't work, then you can narrow it down to the PS or mobo.

I have an ATX power supply tester that I use for such purposes. I do have an extra that I could sell to you, but I doubt that you really want to wait for it to get to you just to find out if you have a bad PS or not.

if you did all that and your still stuck, you can use another machine or mobo to cancel out some of your problems switch and swap 'em... that could take a little while though..

hey guys, thanks a lot for ur help, but ive solved the problem. it turns out the back of my mobo was touching the case so it was shorting out.
