Changed graphics card-then disabled the monitor by accident, now black screen.Not even safe mode works now!
I replaced the graphics card on a spare PC, but couldn't install it so changed back to the old one, but before doing so, disabled the Monitor instead of the graphics card hoping that this would disable the old graphics card. Anyway, now I get a screen view until Windows kicks in and then it goes totally blank (though I can hear Windows start via the speakers)
I've tried to start it in safe mode but it just stops with a list of driver names without going into safe mode (just seems to hang)
I tried using the last known good configuration but this didn't help either. Question is, how do I re-enable it? BTW, I have it networked to other PC but can only get into shared docs

Re: Changed graphics card-then disabled the monitor by...
That's pretty funny (apart from the suffering)! It's doing exactly what you asked and displaying nothing to that monitor. Even if you safe-boot, the VGA thing might try to honor the setting (though it shouldn't if you have WinXP SP3.) Booting to a command prompt 'only' from the safe boot choices and importing some regedit settings from another machine's video might just do the trick. (As well might adding a 2nd monitor on some machine and seeing what changes in the registry using a monitor program for that.... Some 'display' key probably contains 'disabled 1' instead of 'disabled 0'.... )
If you can get a LiveCD or bootable USB key of any sort (WinXP, Knoppix, Kevin's Rescue CD, etc.) you can probably just enjoy graphics settings by booting to that, and edit the registry or use WINCONFIG a little more freely than Safe Boot offers.

First the graphics card needs to be checked, hook a spare monitor to the video output on the back, if normal! LCD display defective and must be replaced, however if the same issue is on the spare monitor the motherboard will probably be needing replacement because most graphics cards are built in.
Try to see if this works on another computer first, if it does, then it assumes the monitor is ok. Then as the computer boots up, boot to safe mode by pressing F8 and once in that state, set the display to a mode that the graphics card will support. If none of the full colour options work, the graphics card may be incompatible, try changing the graphics card.
This can happen if you somehow changed the input setting. Make sure to check the "Input" setting on the on-screen menu and make sure it's set to the proper type of input (HDMI/Digital or D-Sub/Analog) for the cable you're using. If that is correct, and you don't get an image, then you should also try to connect your monitor to another computer using another cable...because it actually may be your computer's video output, or a bad cable, that is the problem, and not the monitor.
If those checks don't solve the issue, then yes it may be "done."
This link will provide you with a user manual for your monitor to assist with the on-screen menu selection.
try this - boot into "safe mode" - (this loads just minimal drivers). Reboot and press F8 while it's booting - it will ask if you want to boot into safe mode - say yes - if the screen works with the low resolution inherent drivers, it's probably a driver issue, or if you have a video card, it may not be able to work at the higher resolutions (which could be a card issue)
This should help you narrow down if the screen actually works, or if it's a graphics card and/or driver issue.
If it works - try reloading the driver for your graphics card (if you don't have a graphics card - try reloading both the chipset driver and the video driver from the manufacturer)
let me know if this works...
(I had a Toshiba Tecra laptop that did the exact thing - you could see the Windows boot menu, and once it completed boot up, the screen would go black - if you started it in safe mode (crummy resolution) it worked but of course the graphics are unacceptable at that resolution)
Turns out this is common with those, it was the graphic card built into the motherboard that's shot....
hi there, looks like windows does not know how to handle the monitor. You may try to disable the onboard graphic card in the BIOS before hooking up the monitor to the nvidia card. then try to run windows in safe mode(by pressing F8 when booting up), it'll run windows with the lowest available resolution, which will be supported by the monitor. Now download appropriate driver for monitor, install and reboot.
The issue is not the monitor, it is the video card. It may be a driver issue (Download and update the display adapter with the latest video driver.) also try booting in the safe mode, See if the issue occurs in safe mode. If the driver update has no effect and issue occurs in safe mode, you may need a new video card. Also disable any screen saver (Set Screen saver to NONE) see if issue goes away. If none of that helps. replace the video card
Seems that you have set the resolution on your graphics card to a
setting higher than the maximum resolution supported by your monitor. Try
to boot into Safe Mode & lower the resolution of your graphics
card. If not possible, go to Device Manager & remove the graphics
card from it, then reboot your computer. This will reset the resolution. You can then re-install your graphics card drivers & get it to work properly.
