I have a Compaq Deskpro EN model ENL\P1. I have replaced the 16 mb nvidia card that can with it for a Tornado Geforce 64mb nvidia card. When I power it on I get no video and the CAP key flashes. The compaq Diag tells me I have a video problem, this I know and the card works on other machines. Any suggestion would be appreciated.

Thanks

Check the obvious to make sure that card is slot securely

In comparing to other boards,are they the same computer models?

Then consider their may a driver problem that has caused the video card problem,check the manufacturers web site for updated drivers for compatibility to OS.

This should also apply to the Compaq ite to see if the particular model will support the video card.

If this is an AGP card, the most likely problem is that it is not fully seated in the AGP slot on the motherboard.

I have had numerous cards give me this problem lately.
The simple test is to remove the bracket from the card, and see if it seatsfurther into the socket.
It doesn't take much for an AGP card to not make proper connections.

Also, compare the connector fingers on both cards.
I have had a few motherboards that refused to work with AGP cards that did not have all fingers present.

As far as I can tell they look the same. As for re-seating - done that several time also. Thanks Rob. . .

Did you remove the drivers for the first card first? Does it work with the old 16mb card? Under Device manager first remove old card. When asked to restart computer, do not restart. Shutdown replace card and see if windows recognize the new card andinstall. Hope that helps.

If there is no video at bootup ie you can't even enter the bios, then drivers have nothing to do with this. This looks like a motherboard compatibility problem.

Make sure your not placing a 4X video card into a 1X AGP slot.

And if your replacing onboard video, make sure that you turn off the onboard video in the BIOS AS WELL as check to make sure the PIN settings on the motherboard are set correctly.

Also, be sure when you plug the card in you didn't force any dust bunnies into the slot itself.

And if your going from an AGP or onboard video to PCI, you may want to check the BIOS settings. Some BIOS require you to specify if your video card isPCI or AGP.
