    Try booting to Safe Mode that is F8 key, immediately after post screen. Then select Safe Mode

    I have done that twice but still same problem. I have been told it could be the backlight in the monitor or heating issue.

    There was no mention of you having tried Safe Mode in your post.
    Please list what you have tried to save time, rather than establishing this post by post

    I presume from what you say this is desktop. Is that correct please.
    If so and it works on another computer, one may presume that the monitor is NOT faulty.
    When you connected the monitor to another computer did you use the same cable, or the one from the other computer please.

    Will this computer boot to the CD and recovery console

    1. Use the other computers monitor cable on this one and the other way round.
    2. If you have this option on F8 try this
    Enable VGA Mode: This option starts Windows in 640 x 480 mode by using the current video driver (not Vga.sys). This mode is useful if the display is configured for a setting that the monitor cannot display.
