Hello

Do you have any other psu to test the system with?

Is there a power switch at the back of the computer?

You said has stopped functioning, was it working previously?

Have any changes to hardware been made?

The power switch is in front of the system, there is no switch in power supply.

Yes,,it was working..I didnt made any changes to the system..I think the issue with the mother board...so plz let me know how to check the power supply is good or not so that I can confirm the problem with mother board.

Check all the PS connections.
Remove the power plug from the computer.
Press and hold the power switch for 10-15 seconds.
Replug and try starting again.
If that doesn't work, you need to check the PS with a PS tester:

Any shop should be willing to do this, and I have seen these for sale at Office Depot and similar stores.

Thanks for the advices. I confirmed the problem is with my mother board and I got an idea how to check power supply from the technician who came to check my system, here is that

interconnect the green and black wires in the power supply and see the fan is working or not.If the fan is working power supply is OK.

Thanks to the technician..

That's not enough to verify a PS is working with sufficient voltage/wattage.
If you haven't checked the voltage, you haven't tested it.
A technician without a PS tester isn't much good.
