I have been trying to fix a friends computer with the following random issue. The screen will randomly change to a yellow tinge every so often. I have tried 3 different monitors so feel that isn't the proble. Have also tried a different video card. That didn't fix the problem either. The system is a MSI 665 ultra c motherboard (845 chipset) with a p4 1.7 cpu and a MX440 video card. Any body have any hints I can try.

If you used a different video card, then you would have used a different output socket.

If you used the same cable, try a different one.

Can finally scratch faulty monitor cable off the list. Nothing wrong with the monitor cable.

if you have ruled out monitor, cable, and graphics card then the only thing left is the motherboard?

either faulty motherboard or just a dodgy / loose connection from the socket to the graphics card? like if the contacts are dirty or corroded or the graphics card is not properly seated...

Doing your best is much more important than being the best.

Do you have a magnetic device (e.g. speaker) nearby? My TV was going green, when I had a speaker cable in close proximity with DVD-TV cable.

Moving the speakers well away from monitor didn't fix anything.

Thats was my last straw. It must be a faulty motherboard.

That would be weird.

To rule out software and drivers, how about booting an ubuntu live cd and see if the problem happens with that? It won't make any changes to your system, and it will be good for internet browsing at least.

I wasn't able to identify an official download location for your motherboard from the information you gave, but a bios update would be worth a shot in case it is some really unusual timing issue which has since been resolved.

I had previuosly updated the motheboard bios to the latest one. I had also booted off a bootable windows cd some time ago when I was trying to fix this problem. The problem was still there. About the only thing I haven't tried is trying to locate a video card driver that would have been the original driver instead of using the latest video card driver.
