Solution : Computer does not Power up start up 

Initial Steps:

_ Make sure that the PC's power cable is plugged firmly into a wall socket or power strip

and that the power strip is on

_ Try plugging the PC or the power strip into another wall socket

_ Ensure that the power cable is firmly connected to the PC's power-supply outlet

  

_ Check to see that the power supply is switched to the "on" position

_ Make sure that the power supply is switched to the voltage appropriate to your region

_ Attach a working power cable to the PC's power supply and plug it in

_ Unplug all external devices from the PC -- including a CD drive or digital camera -- except

the monitor. If the computer powers on without the devices, add the peripherals back in

one at a time until you can identify the problem device

If none of these steps solves the problem, check to see if your computer is still under warranty

and send it back to the manufacturer. If the warranty has expired and you are comfortable doing

so, proceed to the Advanced Steps below. Otherwise, talk to your volunteer consultant.

Advanced Steps: 

_ Unplug the computer and open the PC's case. Verify that the power supply is connected to

the motherboard

_ Make sure that all internal cables are connected and that all of the PCI expansion cards

and RAM chips are tightly seated

_ Examine the motherboard for noticeable signs of damage, such as cracks or burns. If you

see problems, there's a good chance you'll need a new motherboard or a new computer.

Consult a technician for further advice

_ Remove the RAM and PCI cards and unplug your hard drive(s).

Depending on your drive, you'll see either a wide, flat, gray IDE

cable; a thinner red Serial ATA (SATA) cable; or a round gray or

black SCSI cable. Plug in the power cable. If the computer turns

on, begin plugging in additional cables and modules until you

identify the faulty component 

_ Replace your power supply with a known working one or a with new one.

_ If none of these steps work, your motherboard or processor is likely fried. Consider taking

it to a repair shop or replacing the computer altogether

Procedure to replace power Supply:

• Turn off your computer and all the peripherals (such as your monitor, printer, modem, and

scanner). 

  

• Unplug your PC and all the peripherals from their outlets. After that, unplug all peripherals

from the back of the computer. 

• Move to a well-lit, static-free area, such as a tile floor or a kitchen table. Remove the

computer case or panels to expose the interior of your PC. The power supply is enclosed in a

metal box located in the corner of your computer case.
