what device? is *********** board won't start? Or a hardware doesn't start like ram or your printer If the problem is your motherboard check all your hardwares and connectors like this:
If the motherboard won't start if you click the power button check the LED(the small light bulb on your motherboard) if its glowing. If not, check the connector of your power supply or check the power supply if its working by looking its fan if revolving.
If you push the button and there's a sign of power but didn't start up that will appear on your screen check the connection of your monitor screen to your desktop computer. If it's connected, remove your RAM from the motherboard and insert it to another memory slot to check if it's broken.
Last, if you push the power button and here 1 short beep but the boot screen didn't appeared from your screen check your graphic card. Remove the graphic card and re-insert it again to its graphic card slot and plug in your monitor connector to it. If it still remain that way, buy a new graphic card.
If this is the first time to turn you on your computer check first the power supply of your computer if connected to their proper connector. Check your memory if clip properly in there memory slot. If you are using Video Card check it if it is properly connected to the connector. Then connect your VGA connector at the back of your computer when you have video card connect the VGA Cable of you monitor to the video card VGA output if does not have connect it with the onboard VGA output. Then press the power switch if the unit is still no visual in monitor try to search or hear a beeping sound in your computer by its on board buzzer. Find which beep you hear from your computer.
No Beep- No Power, Loose Card, or Short. One Short Beep- Normal Post,, Computer is OK. 2 Short Beep- POST error, review screen for error code Continues Beep- No power, Loose Card, or Short Repeating Short Beep- No Power Loose Card or Short One Long And Short Beep- Motherboard Issue One Long and Two Short Beep- Video (mono/CGA Display Circuitry) Issue. One long and three short beep- Video (EGA) Display Circuitry Three Long Beep- Keyboard/ Keyboard Card Error One Beep, Blank or Incorrect Display -Video Display Circuitry

first remove the cover of your computer after switching off the system and removing the power plug the power the system and see whether the processor fan is working if not power off the system and remove the 24 pin connector from the smps to the motherboard and short the green and black pin of the conector from the smps and see the smps fan is working if not replace the smps if working then remove the memory from the slot and clean them or change the memory to which match the dimm slot an connect the connector and switch on the computer
Are you sure the 4 pin connector is going in correctly? Some motherboards have an 8 pin socket, and the connector can be placed in improperly. The symptoms you describe indicate a dead short on the power line when plugged in.
That model motherboard does not support on/off control of the power supply. Refer to the output diagram on the power supply, and there should be pins in the connector (not used on your board) that may refer to the on/off control. Those pins should be tied together. Then the PC will turn on via the main power switch, and will require a manual turn off when the display says its ok.
Can you describe your hardware (brand names a part numbers of the hardware and speed)Do you here beeps at the post. Here is something you can try. Remove the motherboard with the processor, memory and video card if you have an external one left in place and connect the power supply.Make sure all your power connectors are in where they need to be. Somtimes there are as many as four connectors from the power supply to the motherboard.Make sure everything is indexed and seated properly. See if it works up to the no operating ayatem error. If not use only one memory stick and try that. Still nothing try one of your other memory sticks only if you have more than one.If nothing and you have a onboard video card enable it in the bois and remove the external one and try that. It micht get you going. A common problem with new setups is a standoff connector that mounts your motherboard to the case is in an unused position and shorts the board at that spot.
Please do NOT TRY TO SWITCH ON your comp in same condition again as you would be damaging it further. Its not your power supply alone there EXISTS A SHORT CIRCUIT IN OTHER COMPONENTS as well . The SHORT CIRCUIT Protection circuit of your Power Supply senses this and switches off preventing further damage . Well you could try this - Disconnect power to all the componenets like HDD , CD/DVD , MOTHERBOARD and FDD etc.,. Plug in the AC input power to your Power supply and on the 20 pin connector look for green colored wire and black wire on the same connector and short these 2 wires ONLY with a metal paper clip or a piece of wire , if the fan in the PS works and spins at full speed till you disconnect or remove the short between the two wires (Green and Black) then your PS is Working FINE . Now connect each of the component's power connector only and repeat the same exercise you will be able to identify which component is shorted.
