XP and more than 2 monitors

[KeyserSoze1877]

I have XP Pro an old Dell GX240.
It has AGP card and I am trying to put in 3 additional PCI Trident Video cards. I changed the Bios for video settings, etc...

Only 2 video cards work. I can see in Devide Manager that all the cards were detected, but the 2 that dont come up say Failed to Start.

Supposedly XP can support 10 monitors and have heard people who have done it but havent found why I can only get 2 cards to run.

Maybe your PSU cannot power 4 cards. How much power does each card require, and how much can your PSU provide?

Ignorance is not necessarily Bliss, case in point:
Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.

Is there any further information available in Device Manager, do the various Troubleshooters launched from there help?
