Cannot get display on computer to display anything

    This morning, my eight-year-old son started our Windows 98 computer and
    stupidly attempted to change the display properties. Whatever he did
    hosed the display more than anything I've ever seen.

    This is a Windows 98 computer, normally displaying at 1024x768, 24-bit
    color. Maybe - not sure - it can go up to 1152xwhatever, but we
    normally keep it at 1024x768. Certainly, beyond that, there would be
    problems.

    By using the monitor's built-in adjustments, I can get the menu for
    those to display (brightness, horizontal, vertical, geometry, display
    timing, etc.). So the monitor still works.

    And if I unplug the monitor cable from the back of the computer, the
    monitor displays an appropriate error message.

    BUT...

    Otherwise, NOTHING displays on the computer. NOTHING! The kids have
    messed with the computer before and I could always at least get the Dell
    screen when turning the thing on. Not now. I've always been able to
    launch safe mode. Not now.

    I have tried starting the computer from the MS-DOS 3.5 inch boot disk.
    I hear the 3.5 inch drive klunking, but nothing displays.

    I have tried putting the Windows 98 CD in the CD drive. It sounds like
    the drive is recognized, but I don't get any results.

    Normally, when I turn the computer on, within ten seconds or so of being
    turned on, it beeps at me. Now it seems to take much longer to do
    anything. I *do* eventually hear the musical flourish that you normally
    get when Windows 98 launches.

    With no working display, there is nothing I can do on that computer to
    troubleshoot it. It there a way to, without a working display, force
    the display back to something that will work?

    Kids, who would have them? But it may be a coincidence so don't cut off his
    mars bars yet..

    So you know that most of the monitor is working fine in most respects. i.e.
    the line output transformer hasn't blown up - which is about all the damage
    you can do by trying to run a monitor at a resolution etc that it cant
    handle. So maybe jimmy keeps his mars bars..

    The initial graphics mode of the PC when booting is very undemanding and is
    not altered by the Windows screen resolution changes. So if this isnt
    showing, it isnt because the Windows resolution has been changed.

    So, it could be that in your worried haste, you have misaligned the 15 pin
    plug and bent a pin. Or worse, broken one off.

    .. Or, pushed too hard on the VGA socket on the PC (if it is a card and not
    integrated into the mobo) and the card has become a bit unseated.


    So, if you took the plug off the back of the computer, take it off again and
    look see.

    If the graphics comes from a plug-in card and not direct from the mobo, shut
    the machine down, open it up and reseat the graphics card.

    After that, all you can really do is to either take the monitor to a
    different machine or take the machine to another monitor.

    Call off the dogs (and thank you, Eric the Seal). He had dialed the
    monitor contrast down to 0. I knew I kept the contrast at an extreme
    setting; when I moved it up past 10 I had a visible display, and at 100,
    it was the way it normally is.

    Still, no computer, and no Mars Bars either, for the young rapscallion
    today. Still, a better fate for the little guy than the "retroactive
    vasectomy" I was thinking of performing...

    Glad you are happy... but to stop me puzzling all day... the on screen
    messages you got when the video cable got disconnected aren't affected by
    the contrast settings? That would be a new one to add to my list of things
    to watch out for...

    In my case, yes (or no...). When I disconnected the monitor cable from
    the computer, there was a klunky graphic bordered in red saying that the
    monitor had been disconnected. It looks like the kind of graphic you'd
    have seen on a 1988 DOS computer. I think, but am not positive, that
    the graphic moved around the screen like a screensaver.

    My computer is a Dell Dimension from 2000. It runs Windows 98. The
    monitor is a Dell monitor.

    Hope the above information is sufficient.

    If Safe Mode won't work, it sounds like the video card may have been
    destroyed. You may need to try replacing the video card.
