Leave the computer on over night and intermittently in the morning the screen will not display. Computer is a Dell XPS running Windows 7 Business 32 bit. Have installed the latest video drivers, still failed. Swarp display connection from video card to integrated motherboard video. Did not fail so assume video card problem. Replace video card but has failed. Any guidance would be appreciated.
