I have an NVIDA GFORCE4 card with Three outputs...VGA, SVIDEO, and DVI.  If I hook up my vga monitor (via an adapter) to the DVI port and the SVIDEO cable to my TV, my Windows XP SP2 machine comes up in what looks like Safe Mode my basic video and a RED screen.  I am unable to do anything with it.  However, if I unplug the VGA monitor and just plug the TV in, the display works, then I use the NVIDA software to tell it that there are two monitors and to clone the monitors (display the same on both).  However, if the machine reboots for any reason, I loose all of these settings.  I am at a complete loss, but (for some reason) I suspect the power supply is not strong enough.  Any other suggestions?

I suspect your card is unable to start up in dual display mode, but once the correct port is initialized, it works.  The Geforce4 cards are fairly old and I would think that any modern card can do this without a problem.

Are you saying you think the card is bad?  it used to work in a different machine, I just move it to this machine.

See if it still works as before if you move it back.  Moving equipment introduces new variables that may not have been there before.

One of the most common problems that I have found with the Geforce4 cards is their affinity for messing up in the different video modes (Single, Clone, Stretch, Dualview).  If you haven't gotten the latest drivers from the NVidia site (http://www.nvidia.com), you might want to do that if you can get it to work in your old computer, but not this one.  I had the same problem with one of my GeForce cards recently.  The problem was in a piece of hardware in my computer that was conflicting with the current set of video drivers I had.  Uninstall any old copies of the NVidia driver package on this old computer and reinstall.

For most issues relating to driver modes, it can fix it.
My old Voodoo 3 3000 did this. Make sure your resolution is 800x600 or lower, older cards often have problems displaying to TV with high resolutions. Also make sure you card is actually capable of outputting to TV and a monitor at the same time, as the card will need two DAC (Digital to Analog Converters). Many budget cards only have one, you can try using a DVI monitor and a tv if this is the problem.

Commented:
The problem would not be with a "budget card in this case".  With the GeForce4 line that has multiple outputs, they are all capable of doing the myriad of different views.  The problem though could be the resolution if the reinstallation of the newest NVidia drivers doesn't work, but usually this is only with extreme cases of resolutions (such as above the 1280x720 threshhold on a non DVI accepting/older model TV).  Also, if the card would work on one machine fine but not the other (which is yet to be posted), it would not be the case of resolution.
Why bother hooking the VGA monitor to the DVI?  Just plug it straight into the VGA port.  Does that make any difference to the problem?

I have tried plugging it into every port and can't figure it out.  I have ordered a new card and will try that.

Commented:
I still stand by my comment about it being the drivers.  If it is a driver problem, and you order another NVidia card, you will more than likely have the same problem again.
