No display in the Monitor

Posted on 2004-11-25
Last Modified: 2010-04-26
I checked my computer by plugging in different monitors.  All the monitors show the same symptom.  They don't show up anything.  Just like I didn't turn on the computer at all.  But actually, I turned on.  

I also plug in different display cards, they are working in other computers.  So, what is the problem?

Is it the motherboard's problem?  What else can I check?

Thanks for all replies.

    I removed all the cards and cables.  There is no beep.  What does it means?

    Sounds like it might be a power supply failure.
    Try replacing the power supply.

    and not on when the pc is switched off?

    Some pc's have the system led on just to show the pc's connected to the mains

    But anyway does your hard drive spin up, do the fans work

    It could be a blown motherboard as you should definately get post failure beeps without the graphics card installed

    You can get a PSU checker pretty cheap at your local computer store, at CompUSA they run about $6.00 USD.

    If that cheks out okay, and you can hear or feel the Hard Drive booting, then it has been norrowed down to Memory failure, or Motherboard, since you have tried known working monitors and graphics cards.

    Good luck,

    Thx all experts.  I'm going to check if it is the power supply problem (check the fan) next Monday when I back to work, hehe.
