I just bought an ATI Radeon 7500 PCI video card so I can use two monitors with my computer. It doesn't work!?

- I have a dell computer, the PCI card fits in the slot...my current graphics are 'on-board'...ie i don't have another graphics card installed...the screen just stays black when it's sitting in the slot. if i take it out, the computer starts. any help would be great.|||Your video card isn't installed.



Here's how to install it:



I'm guessing you're running at least Windows XP, so make sure you're logged in as an Administrator. Otherwise, this will not work.



- Locate the My Computer icon

- Right-click the My Computer icon, and select Properties

- Select the Hardware tab, then select the Device Manager button

- Double-click the menu item labeled Display adapters. Your current display adapter will appear immediately below as a separate menu item.

- Right-click the display adapter text that has just appeared. A menu with several options will appear.

- Select Remove or Uninstall from this menu. Figure 3 shows the Device Manager with the Uninstall option highlighted in Windows XP.

- Select Yes if any additional prompts appear. If Windows prompts you to restart your computer, select No.

- Shut down your computer normally.



Now you're ready to install your new graphics card. Be sure to have your Installation CD on hand before proceeding.



- Physically seat your new card in your computer.

- Turn your computer on. If you see an image on your screen, then your new video card is properly secured.



Now that your video card is up and running, it's time to let Windows know which card you installed. Windows requires a certain set of software, called drivers, to tell it exactly how to utilize your new video card.



Each video card manufacturer has a different method of installing the video card drivers in Windows. Accordingly, check your video card manual for specific instructions on how to install the drivers. The actual driver files are usually included with the video card in the form of a driver CD. Drivers can also be downloaded directly from the manufacturer of the video card or video card chipset. For more information on this please see the appendix.|||ok, so you have this new card for a second monitor I take it.



Ok, in order to have any new add-on hardware work you will need to install the drivers first.



1. Put the new card in the PCI slot. (But keep you monitor plugged into your original device, in your case the onboard video port.)



2. Start Computer and load the installation CD that came with your Video Card (or download the latest drivers from the manufacturers website.)



3. Once it detects and installs the new hardware (in your case the video card) and completes you will shut down your computer.



Note: Don't uninstall or disable your onboard video yet if you dont have to in case you still need it for possible troubleshooting.



4. Connect your monitor to the new device and start system back up and see if it loads correctly.



5. If all is well and you do not wish to keep your onboard video for whatever reason you can now go into "control panel/system/device manager and disable your onboard video device.



**IMPORTANT**: For this to work you may need to restart the computer and at the first posting screen hit your delete key or whatever key your system uses to go into the bios and locate the section that has your "Onboard Video" selected as primary display adaptor and swap it to "PCI" instead. Hopefully you wont need to do this until you have completed everything else.



Each different motherboard handles hardware a little different but this should be pretty straight forward.|||You probably have your computer set to consider the new graphics card as primary. Before the operating system loads, there is no ability to access a secondary monitor, so only the primary monitor will work.



Connect your monitor to the new graphics card. Power on your computer. Load your operating system. Then configure both displays the way you want them.



If, for some reason, you want the onboard graphics to be primary, you should configure that in your BIOS.
