    are you positive its your monitor and not your graphics card?

    Usually when a pc starts up the motherboard checks that everything is there its usually goes something like this:

    1: processor
    2: memory
    3:gfx card

    now personally if my monitor doesnt come on i check those three things.

    Also, read the "How to post a question" sticky. The title of your thread is not acceptable. And do not type in all capitals. It is annoying to read.

    well i can guarantee then that it is one of the three that is faulty:

    1: motherboard
    2: processor
    3: memory

    check the memory is in the slot properly,
    check the processor for burn marks on the underside
    then if you have another pc try and test the parts induvidually in that.

    are you positive that you have changed nothing between the first time and the second time?

    IF you are using Windows XP....

    Your computer is probably setup so that when you hit the Power key, it goes into Hibernate mode.... Or, the Windows power settings are set to go into hibernate mode after an hour or whatever.

    When a computer is in Hibernate mode, it looks like it is completely off. When you press the power button, it doesnt beep because it is not going to have to start up all the way from scratch. It just reapplies power to the system, reads the hard drive to figure out where it left off, and voila, you are in.

    Some video cards don't like Hibernate... perhaps its the motherboard not giving the right initialization to the video card, so the computer looks like it "just turned on", without video.

    You do "shutdown... turn off" to bring it down... then power it back on, and it works great.

    Do you have kids or someone in the house that might just push the power button instead of properly shutting down? If they just hit the power button, and its set to Hibernate when the power button is pushed, that's your answer.

    To find out, do the following:

    1. Right Click on the desktop
    2. Select "Properties"
    3. Select the "Screen Saver" tab
    4. Click the "Power" button
    5. Select the "Advanced" tab
    6. Under the "Power buttons" section, check out what options you have there. If either the power or sleep button are set to hibernate when pressed, that could be the problem.

    It certainly explains what you are describing. Good luck!
