Knowing more about the system would be very helpful. Try to find a knowledgable family member or friend to help.

Update your post as best you can to include full system hardware specs and OS information.

Immediate thoughts:

1) Unplugged, damaged power cable, power strip, etc. - power not getting to the desktop computer.

2) No power at the wall outlet serving desktop computer, monitor, and other possible peripherals.

3)Failed/broken power switch on the computer.

4) Some internal connection in the computer has come loose.

5) The PSU (Power Supply Unit) in the desktop computer has failed. How old is the computer? History of heavy gaming use?

More information needed.

It is Lenovo Thinkcenter M700 , i5 6500 , 8gb ram , 256gb nvme ssd . Cabinet fans and cpu fans are running , power button led is not lightening , no beep no display , power outlet , power cable , are good .
