trouble installing radeon 7500 in compaq

[keir]

The monitor will not display anything when i install the card and plug the monitor into the card. And even when I try to plug the monitor into the computer it will not work.

I have tryed using bios but i do not understand it that well

is there on board video?

[keir]

yes there is an on board video but i do not no how to disable, other than on device manager, but that doesn't help.

go into the bios and look for on board video.

You need to do a couple other things before disabling the onboard video (if you want to even disable it at all).

1. Install the new card (I'm assuming that it's a PCI video card, to replace the onboard.)
2. With the monitor still plugged into the original video port, boot the computer and install the drivers for the new card.
3. Reboot with the monitor still on the original video port.
4. Right-click on an open part of the desktop and select "properties".
5. Click on Settings tab and select the new video card from the display box.
6. Check the box marked "Extend my Windows desktop onto this monitor".
7. Now check the box marked "Use this device as the primary monitor"

This should set the new video card as the primary, and you can switch the monitor over to the new card to see if it's working.

If you're installing an AGP card, the motherboard should disable the onboard video automatically when a card is installed in the AGP slot. No other settings changes should be required.

that would probably work if i could get the monitor to work, even when i plug the monitor into the original port, it doesn't work

No that doesn't work, since you also need to set the VGA preference to "PCI first" in the system's BIOS. Doing that in Windows alone won't help it.

You should do this before adding the card in; if there's no such switch it should be automatic - and if it doesn't work, then you're screwed. Welcome to the wonderful world of brand PCs.
