Actually when nothing happens at all. It's an easy problem to find. You have no power. Plug a lamp into the light socket and test it for juice. If your computer is getting power to it then
Make sure your power supply is set to the right volts (normal is 120 )

1. Open the computer case and (with the power removed) unplug the power supply and remove it from the system case. It's only afew screws and the cables connectors are specific to each other so no mix up to worry about.

2. If you have a dc volt meter then find a cable that would feed on of your drives and carefully check the dc volts there. you should check the read and black wires. Around 10vdc i think .

3. if there is no voltage there then your problem is in the silver box that all tose wires come out of. unplug the power. unplug all cables coming from the box. then remove the box.

4. now you can either open it up and you may be able to replace the fuse to fix it or you can buy a new one for about $50.

i guess the problem is there in the power supply i.e, smps of your cpu. change it and check whether it turns on. if your pc fails to start after changing a new smps then the problem should be your motherboard.
