@56kul , welcome to the Community.
It appears from the specifications that you do not have a discrete video card installed and are using the Integrated Video on the motherboard. Is this correct?
The problem may not be the video card, it may be that you have a short caused by the power button being dislodged from the case. I suggest that you discontinue using the computer, so no further damage is caused by it. If you are not comfortable with working on computers, I suggest that you take it to a qualified computer shop.
