Is the Geforce mx 440 already installed and working on the "old" pc?

If it isn't, is the Geforce mx 440 PCI or AGP?

If it's AGP it's 2X/4X/8X AGP compatible - if it's installed on mboards with certain main chipsets with only 4X or 4X/8X AGP support installing a 2X capable chipset card can damage the AGP circuits, the mboard, and the card.

In that case, or in any case, what make and model is the "old" pc, or the "old" pc's mboard?

Does the CRT TV have a S-Video jack, or a female RCA video in jack (usually it's yellow), or both?
If it has neither, see below.

You'll get slightly better video on the TV with an S-Video connection.
If it has a S-Video jack, use a standard S-Video to S-Video cable (4 pins, connectors male on both ends) .

If it has only a female RCA jack, get a standard S-video to composite (S-Video 4 pin male to RCA female) adapter, the card may have come with one if you still have that, plug it into the "S-Video" jack on the mx 440, use a RCA to RCA (male on both ends) cable, preferably a better shielded thicker one meant for video, between the adapter in the card and the TV jack.

To display the TV Out video on the TV
- the TV must be set to a video input mode other than the TV tuner - e.g. video 1, video 2, S-video
- you will probably need to activate (turn on) TV out in Windows once the cable is hooked up, or whenever you have unplugged the cable for a while and then plugged it back in, accessed by RIGHT chicking on the second display shown in Display Properties in Windows.
.......

If the TV has neither a S-Video jack or a RCA jack, you need an RF modulator box, a standard S-Video to composite adapter for the card's "S-Video" port, and a RCA to RCA cable (male on both ends) between the card's adapter and the female RCA jack (usually yellow) on the RF modulator box.
When you want to use to TV in TV Out mode, you move the switch on the RF modulator box to other than TV.

You will probably need to activate (turn on) TV out in Windows once the cable is hooked up, or whenever you have unplugged the cable for a while and then plugged it back in, accessed by RIGHT chicking on the second display shown in Display Properties in Windows.
......

An RF modulator box is the same thing you use when you want to hook up a VCR or a DVD player to a TV that has no S-Video or RCA video input jacks. You connect the incoming TV cable to the box, or the antenna connection to the box via a matching transformer adapter, and the box to the TV's coax or antenna connection.
........

If you want audio on the TV as well for the TV Out video

- if the TV has two female RCA audio IN jacks (usually red and white), you need a cable with two RCA male connectors on one end, and an 1/8" (mini "phone", male) stereo plug on the other.

- if the TV has no RCA jacks, you need the same type of cable between the computer and the RCA female audio IN jacks (usually red and white) on the RF modulator box.

You plug the 1/8" stereo plug into the audio out or headphones jack on a desktop computer (audio out only has output if only two speakers are connected to the computer sound) , or the headhone jack on a laptop computer (which usually disables the sound on the laptop while plugged in).

You will be completely disatisfied with using a CRT TV for a monitor. You will be limited to a resolution of 640x480 and the display will be of very poor quality. I suggest that you don't even bother trying.

Thank you for the reply, I know that it's a AGP as I opened it up to take a look. I don't have a S-Video slot on my tv but have a scart composite which has a composite and S-Video on it. It seem to work but the screen don't fit well has it keeps on going over the edge, anyway ti fix that also the picture quality is not good.

You may be able to adjust the screen size in Display Properties - Settings - Advanced somewhere. Otherwise, you have to adjust them on the TV.

TV Out video is always inferior to modern monitor video because the video is processed to conform to the much older TV display standards, the pixels on a TV are coarser than on a monitor, and the vertical refresh rate in TV Out mode is in your case locked to 50hz (and in my case to 60 hz) . Video may look okay but the text on the screen tends to look coarse in comparison to a monitor display.
