sudden shut down & no booting up

[curioustechy]

While I was using my system immediately power supply failed & UPS too failed. Now once the power is restored, nothing comes on my monitor except 'no signal' .. CPU power led is on. NUM lock led is on but can't turn it off. I switched on 3 to 4 times but couldn't succeed. What can be done.

check whether also Fans are working or not to test the PSU issue...
otherwise it will be mobo issue

Fans working, my mobile is being charged from USB, mouse lights on, DVD tray ejects when the button is pressed

Check the monitor cable. Check whether analog mode/digital mode (whichever you use) selected in monitor appropriately.

How to reset bios

No beeps at all

Check the monitor cable. Check whether analog mode/digital mode (whichever you use) selected in monitor appropriately.

I think you mean monitor data cable. I tested with another working one. No changes. I didn't get your second statement

There are two ways to reset BIOS:
1. You need to use BIOS jumper to reset it. You will find the location of the jumper from motherboard manual.
or
2. After removing PSU cable from wall socket, remove the BIOS battery from its slot for at least 5 seconds, and then place it back.
