I would try a different monitor or TV. The cables either work or don't so I would not think that is the problem.

If your using a video card and have a processor with built in graphics you can remove the video card and see if it will run off the motherboard.

I tried to connect another pc and the monitor works with no problem.then I tried to re-install graphic driver it didn't change anything

installed driver was nvdia geforce 630 and i have windows 10 64 bit

monitor and its cable has no problem.
problem now is screen flickers and goes black after restaring pc in few minutes.After going black unplug-plug the monitor cable it runs for less than minute .after few unplug-plug screen comes for a second then goes black again.now i am tring to install all windows updates if it works i will write here.
