Hi all,
New to this site, but found at least one fix for the above problem. My computer was able to start in safe mode but not in regular Windows mode. I would see the Windows XP splash screen but as soon as it was suppose to load the desktop, the monitor would shut off as if it wasn't recognized. Here's what I did to solve it....
--I booted up into Safe Mode (F8 during startup)
--Once in safe mode, I went to the Device Manager (Control Panel, System, Hardware Tab, Device Manager Button)
--Click on Display Adapter
--Right click on the Display Adapter(s) listed and select Uninstall (I would suggest having your original Driver CD as a backup in case Windows cannot automatically reinstall the drivers...if you don't have a driver CD, I would suggest downloading the Drivers from another computer and creating a CD--again, just in case Windows can't reinstall the drivers)
--Once you click to uninstall, close the window and restart the computer
--The cpu should boot back into regular Windows and reinstall the Display Adapters automatically. If it prompts you for your CD, insert it and load the drivers from there.
--Once it is loaded correctly, restart the computer to see if it fixed the problem permanently.
I have a newer LCD monitor on an older XP Home computer and this fixed the problem for me. Good luck and hope this helped.
