Newly built computer won't turn on

by Bitter Patrick / June 3, 2004 9:23 AM PDT

Nothing. No beeps, no fans, nothing. The most I can hear is a sort of faint click from the power supply. I tried removing all the components, putting them back in, and so on, but I have absolutely no clue why it's not working. Advice?

Oh, I'm not entirely sure I hooked everything on the front panel up right, but, there should at least be a beep or a whir or something, right?

Two quick areas to check......

Make sure the power supply "voltage selection 115/230" switch is correct...115V

Next, make darn sure the frt. panel power-ON cable is on the proper connection, usually a 2-pin hook-up. Labeling may sometimes confuse it with "remote" power-ON or similar. Just shorting the 2-pins momentary will allow a power-ON as that's what the frt. sw. does.

I *assume* alot here, so verify again all connections and proper ordinations, etc. is correct. Make a simple system w/o any HD or CD, just the ram, video, kybd. and FD present for a basic system.

good luck -----Willy Shocked

Light good, whir is from fans, beep would be super.

But if you remove the motherboard from the case (to avoid shorting out the backside in the case), add CPU/HeatSinkFan, plus a speaker, with just that and a power supply (no memory, video, etc.) You'll get beeps of protest unless the BIOS battery is dead, the reset jumper is on wrong, the CMOS clear jumper is set to CLEAR...

If not you are staring at the four possible bad parts.

Bad can mean wrongly jumpered too.

If you have all the power supply components properly plugged in (main power connector on MB, 12v connector if Intel and power on switch connected to proper pins on MB) try watching the PS fan while you switch things on. If it sort of twitches and stops, this means it is trying to turn on but has detected a load problem. Usually something is shorted. It could be the MB to the chassis due to a hidden mounting post still under the MB. It could be an improperly seated component. You can also check to see if your MB has an LED on it to indicate presense of the control voltage needed to turn on the other PS circuits. If LED is not working, there is no power to MB. Keep checking and good luck.

I would check and re-check the wiring to your case power switch, it is very easy to confuse cables meant for power on switch and the reset switch. The faint click could be coming from the switch itself.

Hi..irrespective of the power leds,the one thing that should start is the fan on your cpu..if this doesnt start then you have no power to you motherboard, check that you have set your voltage correctly 210/230,,good luck
