display going out

I have a windows 2000 professional computer and when I turn it on I see the boot proccess, the starting up windows splash screen and the bar loads all the way until the end.  But the display then goes out and the light on the monitor is amber.  I tried another monitor and the same thing occurs.  any ideas?

Thanks, Justin

This is what you might see if there are two video outputs on the PC.  It will boot using the BIOS's "primary" video output and then as soon as Windows starts up it switches to the monitor that was set up as the primary Windows Desktop display.  They are not necessarily the same.

Are there two different video ports (VGA and/or DVI) on the PC?

Ok.  It is unlikely that it is switching to the svideo output.

Does it do the same thing when you boot in SAFE mode?  SAFE mode will restrict the video output to a very basic setting, so it may behave differently.

My working theory is that the Display settings somehow got switched to a resolution or refresh rate that is not compatible with the monitor.  I don't know why it might have happened, but this is what you would see if that was the case.

Yeah it shows up in safe mode.  How do I fix the users profile?

Cool.

I wonder if, while in SAFE mode, you can simply go to the Display control panel and change the settings to be "safer" like 1024x768, then boot normally and make the final adjustments.

Worth a try.

In safe mode it was 640x480 so I changed it to 800x600 as those are the only two options.  Did not work.

ok.

I think you'll need to use regedit from SAFE mode to fix the Display settings.

The key is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video

There are settings called "DefaultSettings.VRefresh",  "DefaultSettings.XResolution", and  "DefaultSettings.YResolution".

But it is a little tricky.

You will need to expand that subtree and find the right GUID to change.    There will be at least one subtree that already has those keys defined.

Here is an extended discussion of how other people have dealt with this problem:

In safe mode uninstall the video driver from add/remove programs if possible, if not there then remove it from device manager, then restart into normal mode and install the latest driver for your card.

I'd find out what the video card is, the model, and go to the MFG website to get the latest video drivers and install them.

I've had to do this recently with a display problem that was fouled up by an application that changed the properties of the video display, and seemed to have inserted itself in the driver that controls the display.

In safe mode, go to "system properties" (control panel) then hardware, then device manager, then Display Adapters and get the name and model of the display adapter.

For example, you might be running an NVIDIA GeForce adapter with a model number.

then go to the mfg website and get their latest driver for your particular display card and install it.

Hope this helps,

Jeff

Thanks guys the uninstalling of the driver worked.  When I rebooted the PC it came up.  I just need to install the updated drivers.  But we are up and running which is awesome.
