|"The monitor comes on during boot up and displays an initial Windows screen. After a few seconds there is a click from the relay and the screen goes black just before the jingle."|
That's not the same thing as
"Monitor does not come on at boot up"
It would more properly described as
"Monitor does not come on after Windows starts to load" or similar.
Your Windows video adapter software is probably screwed up.
Boot the computer to the menu where you can use choose Safe Mode etc.
As in, boot your computer, and shortly after the green light comes on steadily on the monitor, repeatedly press F8 (don't hold down the key)until the menu appears on the black screen.
Choose Enable VGA mode.
That will start up Windows normally, except the video is forced into a basic VGA mode that all video adapters support - any specific drivers you loaded for the adapter are not used in that mode.
If that gets you to the desktop, go to Add/Remove Programs in Control Panel, and find the entries for the video drivers for your video adapter, and any other entries associated with them, and Un-install them.
(You usually can't do that in Safe Mode)
If you need help with that, let me know - it would be very useful if you could tell me the make and model of the card.
Then reboot normally.
If that works, Windows will find the video adapter while booting, Found New Hardware will pop up, but it won't find the drivers for it, and it will ask you where the drivers are - Cancel that, and continue on to the Desktop, and load the drivers for the adapter using the Install or Setup program that came with the card, or newer driver downloads you already have somewhere on the hard drive if you have them, or get new drivers from the manufacturer's web site and install them, or similar.
I you need help with that, let me know. If there is more than one download for the card, it's often important which order you install them in.
"I had thought that I had installed the monitor driver, but had somehow failed to do so. "
Sometimes installing the video adapter drivers and associated programs loses track of the specific monitor drivers you have previously installed, and they may not even detect the monitor as a Plug and Play monitor - they are still there on the hard drive, but they must re-installed by using an installation program that installs them again, or if that's not available, be pointed to on your hard drive by going to Display - Settings - Advanced - Monitor - Driver ......Have Disk, and browsing to where the monitor drivers are, or similar.
Sometimes that can only be done in Enable VGA mode.
"I could not find the video settings in the bios, in spite of poking around. Are these settings always available?"
They are always available, but they may not be labeled exactly as I described.
If you have the mboard manual there is usually descriptions in it of what the settings in the bios Setup are for and what they do when set to the various settings - if you don't have or know where you put a printed one that may have come with it, the manual is usually a pdf file on the CD that came with the mboard.
If you don't have the CD, if you supply the make and model of the mboard, I can probably find the descriptions of the bios settings in a manual on the web.
If you're not sure what make and model of mboard you have, look on the mboard for obvious larger printing on it's surface that may be the model number - it's often between the slots or near the center of the mboard - the maker may or may not be obvious - and tell me what you found.
If you find nothing obvious printed on it,
I need your bios string to be able to possibly identify your mboard and/or computer system.
Go here, download BIOS AGENT.
Run BIOS AGENT to find your bios string.
- here's the link that downloads Bios Agent
Tell us everything Bios Agent finds, and include any dashes, etc.
Bios Agent must be used in Windows.
The following works even if you have no drives at all connected to your mboard but you are able to boot and get a display on your monitor.
If you cannot use Bios Agent, the bios string is usually a long string of numbers/letters at the bottom of the first black screen as you boot your computer - usually you can press the Pause key to read it and copy it down. Press any key but Pause to continue booting.
It could also be higher up the screen under or beside the bios version line, e.g. under or beside Award Award or AMI or Pheonix...
Post the bios string here, and include any dashes, etc.
Please make sure you copied it right. Most Award and AMI Bios strings do not have spaces. Newer Phoenix bios strings, based most often on those for Intel mboards, are often like so: xxxxxxxx.xxx.xxxxxxxxx
Sometimes the bios string is not visible because a logo screen is displayed overtop of it while booting. In that case, if you are not able to use Bios Agent, go into your bios Setup while booting. Sometimes the bios version date, and sometimes the bios version number, are stated in the bios Setup screens somewhere, and/or some show the identifier part of the bios string at the top of one or more screens.
Or you could try disabling the display of the logo screen if there is such a setting, or disabling fast boot or similar, which often disables the logo screen.
Tell us what you find.
"The Graphics card is reported by Device manager as PCI, but it looks like an AGP when I take off the lid."
If it is an AGP card, the slot is usually light or mid brown, it's a different length than the PCI slots are and placed farther from the outside of the mboard, and it's the first one on the middle of the mboard end.
If it is a PCI card, the slot is usually white or creme colored, there are usually several of them, and the card can be in any of them.
If it is AGP, and Windows says it's PCI, the settings are wrong in the bios setup for the card.
