    Sounds like a "DPMS" issue.  Have you tried changing the "Video Off Method" in the BIOS?  See this:,1126-8.html

    You may need to dig around to find the setting in the BIOS for your PC, or it may not be there at all.

    Try to make all the Power Management settings as basic (disabled) as you can.

    Also, have you turned off all the power saving options in the Display control panel already?
