I have updated my windows xp to windows 7 home premium 32bit. But after installing the windows 7 I recognize that my onboard video card is not working so I tried to install the the drivers for ATI Radeon HD 3200 video card and when I try to connect my cable to the VGA port so it give me the message of no signal found where as I was not having any problem with the windows vista. I want to know what is the problem with my PC and need proper solution for it.
