Check the manufacturer's website to see if you have the latest bios for your board. However, the most likely culprit is your power supply or motherboard. If there is a bad trace in the copper on the motherboard, this might happen. I would first try using another power supply if you can get your hands on one. If not, take it into a computer repair shop and have them test your power supply after you explain exactly what has happened so they are sure to test the right cables on your PSU.

Good luck.

What make/model of power supply (SMPS) are you using? This does sound like a defective power supply.

What do you mean " when i run the pc without 4pin cpu connector, its worked but no display in monitor...
after plugged the 4pin cpu power connector, smps,hdd,cpu,cpu fan,dvd drive etc.. not working/running..!!! " ?

Do you use the right PSU connector?

A sparking sound in the PSU sounds like a pretty dead give away. Maybe you should have mentioned that first. lol Go get a better power supply. I don't think you should be hearing any sparking sounds coming from any PSU.

Did you connect the +4 connector (part of the 20+4) into the 4-pin socket? If so, that is the wrong connection.

Swap PSUs with another system if you can. Report back with the results. Good luck.

Okay, lets try this again. You have 2 connections to make on this motherboard. A 4-pin connection, near the CPU and a 20+4 (or 24-pin) connection near the IDE connection. Are both firmly attached to the connections from the power supply?

If you have a known good PSU properly connected and it still fails to work, then the motherboard is likely defective. If that is the case, there is no feasible way for the OP to fix the motherboard other than replacing it or returning to Asus for exchange/repair.
