Could be a power supply issue, check power supply connection to video card, if okay try to reseat video card in PCI express slot. Power supply should have 450 watt rating or more.

Can you test video card in another computer? or can you try a different video card in unit?

Can i be sure it is related to GPU only..or something else is causing the problem(like motherboard).This problem is happening randomly.Like i am watching a video and i simultaneously opened chrome.(note the same scenario is not happening everytime).sometime it happens while copying data to external HD(video is playing also).And sometime during startup nothing will be displayed.But you can hear windows startup.Thing i am not understanding is it was fine till past 2 years.why all of sudden.i am not doing anything different now.i dont have a video card access or another computer.
