I just installed WinXP on one of my machines that has a Radeon 8500 in it. I leave the DVI-VGA adapter plugged into the DVI port so I don't lose the adapter despite not actually having a monitor plugged into it. In Win2k this didn't cause any problems, but in WinXP it does. WinXP for some reason thought there was a monitor plugged into the DVI connector and made it the default monitor. Now I can't get Windows to stop defaulting to the DVI port at boot, so if I have my monitor plugged into the VGA port I can see things on the monitor until it loads the desktop, then the screen goes black and eventually the systems reboots itself. It does the same thing if I try to boot using safemode. This wouldn't be a big deal except you can't seem to enable TV-Out while the DVI connector is being used which is a rather important feature for me as I use a TV as monitor for this system more than my monitor. I tried uninstalling the drivers and reinstalling. Upon rebooting the system boots fine from the VGA port, but if I reboot again it goes back to the DVI junk again. How on earth do I fix this?
