No Display on the monior when I connect a monitor to an add on video card using DVI cable

I have a Dell desktop GX280 and it has an add- in AVI graphics card RV370s with DVI port, motherboard has VGA port. When I connected to Acer (AL1916w) monitor using VGA cable I get the following error message. If I remove the add-in video card then there were no issues.
But my goal is I wanted to connect to monitor using add-in video card
• If I connect the monitor using DVI cable (add-in video card) without VGA cable then system starts but NO display on the monitor.
• Not able to install video drivers without inserting Graphics card, If I Install the graphics card then I can’t see anything on the monitor.
I would greatly appreciate your help on this.
System halted!

When you install a video card in the PCI-E X16 slot on your mboard , the bios disables the onboard video automatically. THERE IS NO SETTING IN THE BIOS SETUP THAT DOES THAT for your mboard !
You can ONLY get video from the video port on the video card that's installed in the PCI-E X16 slot when the card is installed !

The video chipset does not need any drivers from the hard drive while booting the computer in order to produce video !
............

If the Acer monitor can be connected via a VGA or a DVI connection on the monitor itself, you can only use one type of connection at a time.

"...an add- in AVI graphics card RV370s.... "

RV370s is the model of the Radeon chip, but it's NOT the name of the Radeon graphics chipset !

Comparison of AMD graphics processing units
http://en.wikipedia.org/wiki/Compar...

Excerpts:

PCI-E (X3xx, X5xx, X6xx, X1xxx series)

Radeon R300 series

(from the table)

The RV370 series chip is used in

Radeon X300, X300 LE, X300 SE, X300 SE Hyper Memory;
Radeon X550;
Radeon X1050

The lower Radeon chipset versions require your system has a lower minimum power supply capacity - the higher versions require your system has a higher minimum power supply .

E.g. I looked this up the other day -

Radeon X1050 - minimum 300 watt power supply required; AND minimum 18 amps at +12 volts

If you DO have a Radeon X1050, the card may have a power socket on it - if it does, you MUST plug in a connector from the power supply into that socket. If your power supply doesn't have a suitable 6 pin PCI-E power connector, you can buy and use a wiring adapter with it, if you have two spare larger molex drive power connectors available.

You need to identify the name of the Radeon chipset !
If you don't know that by it's manufacturer's model name....

........

"Dell desktop GX280"

Your power supply may not have enough wattage capacity !
There are FIVE different case versions of the Dell Optiplex GX280 series, shown here:

Dell™ OptiPlex™ GX280 Systems User's Guide
http://support.dell.com/support/edo...

Specifications...

Excerpts:

PCI Express
connectors: one x16

(So you have a PCI-E X16 slot, not an AGP slot)

DC power supply:

Wattage
small form-factor computer: 160 W
small desktop computer: 210 W
desktop computer: 280 W
small mini-tower computer with processor speeds of 3.2 GHz or lower: 250 W
small mini-tower computer with processor speeds of 3.4 GHz or higher: 305 W
mini-tower computer: 305 W

If your power supply does not have enough wattage capacity, or if it doesn't have enough current (amperage) capacity at +12 volts, for the Radeon video chipset when the Radeon card is installed, you may get NO VIDEO from the graphics card and your computer may NOT BOOT normally !

The setting for Primary Video, or Intialize Video First. or similar, in the bios Setup should be set to PCI-E or similar when a PCI-E X16 card is installed - it may do that automatically - in order for the enhanced features of the specific video drivers installed for the video card to work properly when you boot the computer normally into Windows, in Windows.
However, that setting has NO EFFECT regarding whether you get video while booting BEFORE the operating system - Windows in this case - loads from the hard drive.
....

If you DO always get video while booting BEFORE the operating system loads when the video card is installed, but then NO video after Windows is supposed to load, that's EASY to fix !

See response 9 here:

How to load Windows in Enable VGA mode....

Remove any bootable CDs or DVDs from drives.
Press F8 repeatedly while booting, don't hold down the key, and when the boot choices menu appears, choose
Enable VGA mode
