Computer starts but no display

[posterkumar]

I have my monitor on a table, the wirings and connections are behind the table,an object fell on the wires , the machine was on and i was browsing internet . when i lifted the object the screen was on but the mouse and keyboard was not functioning.
i shutdowned directly using the cpu power button. after that i again switched on and
pressed the cpu button i found the monitor's display was gone. i could hear the beep and also the welcome sound as my speaker was on. The welcome screen convinced me that it was booting up as usual .after wards i checked all the cables .in the meantime i had to start and shutdown the pc repeatedly directly . after sometime i discovered that i can still listen the beep but the welcome screen sound is gone(my speaker is always on) .Now i realise that at present it is also not booting . I am in a total mess , the pc is not booting , display not showing .Please help me urgently

N.B. My pc has no virus . I scan everyday using Malwarebytes

Check and reseat all connections at rear of CPU. Seems you pulled something loose.
Did you have to move your cpu to get the object off? If yes, you may need to reseat all connections
and boards in the cpu as something inside may be loose. This would be my first step.

Also make sure that both the computer and monitor plugs are firmly pushed into the power socket, and that the cable from the computer to the monitor is firmly pushed into the monitor as well as just the computer. If when testing them you pulled the cable out before pushing it back in make sure that you pushed it into the correct socket, e.g. VGA or HDMI.
