The problem could be in any number of places, and you have to be methodical about eliminating possibilities.  It usually helps to know what happened between the last time it worked and the first time it didn't.  Here are some possibilities:

- bad connections
- faulty or inadequate power supply
- bad RAM
- faulty video card
- bad cpu
- bad motherboard

Reduce the system to a minimal configuration: one module of RAM, the cpu, and the video card, and reset the BIOS.  Do not include hard disks, other PCI cards, or other peripherals.

If it doesn't start up, swap the power supply.
If it still doesn't start up, swap the RAM.
If it still doesn't start up, swap the video card.
If it doesn't start up at this point, you may have a faulty cpu or motherboard.  The cpu can be tested by trying it in another system; the motherboard really can't be tested, and you would point to it when everything else has been tested out.

Maybe PowerSupply is broken,just test with another, or something with motherboard goes wrong.

POWER SUPPLY


No doubt


but if it isnt


then it has to be the mainboard


those are the only 2 things that can stop the computer from posting or at least giving you a beep code ..

its sounds like power supply tho ...easyer to test that than the motherbord

but if you swap out the PS and still nothing ....more than likely the MB

Hello,
Folow Callandor instructions. That is way to do it. No question. Also if it is Power suply only and it could be. find out whay power supply failed, so you can prevent from happening again.
