Blank monitor after installing new video card

I have a Dell Precision 380, which has only one PCIe video card slot, and no on board graphics adapter. I want to remove the current nvidia Quadro NVS and install a new ATI Radeon X1900, but when I put in the new card and boot the PC, the monitor stays black.

What can I do? I tried installing the ATI drives first, but they won't install without the card in the system.

    I assume I have to do that before I remove the nvidia card, so I can see what I'm doing -- but how do I do that, exactly? I haven't done anything like that in about 15 years.

One thing you can try is to go into the Bios and load the default Bios settings. Sometimes that helps in reassigning interrupts and I/O addresses with new hardware.

    When you reboot your PC, press the F2 key, this will bring you into the Bios.
    In the very first screen of the Bios there is an option to load the default settings. Simply select that and confirm the selection. After that you can save and exit (I think using the F10 key, but it will be shown in the screen).

    And yes you should do this with the old video card in the system, since your screen was black with the new video card.

    If this does not help, you could check if you have the latest Bios version and consider updating it.

    But considering your experience, you might want to get someone to help you who has experience with this kind of thing (present I mean, not online).

Just go a dell precision 380 hook up for the monitor has 3 prongs and the computer has 2 what do I need to hook it up.

On the left side are different views. I am looking at the REAR view

At the Bottom, of the Rear of the computer, are 6 expansion slot openings.
Two of the expansion slot openings have an adapter card in them.
The other 4 are covered with an expansion slot cover. (Metal)

One of the adapter cards is a Graphics Card.

Looking at the Back of the computer, and from Left to Right;
there is a;

1) S-Video port
Black in color, round in shape

2) DVI port
White in color, parallelogram in shape

3) VGA port
Blue in color, parallelogram in shape

This article shows a graphics card with the same setup,


You can use the S-Video port, or the VGA port, or the DVI port; to connect a monitor.
However out of all three, the DVI port is the best.

VGA is Analog.
Your computer puts out a digital signal. (Digital video signal)

DVI is Digital Visual Interface. In otherwords - Digital.
Therefore DVI is the best.

Armed with the above information, can you clarify more about your problem?

For example;

Monitor cable has three prongs........

Using the above information, can you tell me what monitor cable it is?

Computer has two...........

Can you tell me where on the computer, you are trying to plug the monitor into?

Please post back in a Comment.

I need vga driver for dell optiplex 380

Which specific model is the Optiplex 380 and what OS is installed on the computer? Does your computer have a graphics card installed or are you using the on-motherboard graphics?

Most of the Optiplex drivers are available here: . Use the drop down menu to select your OS. Expand the section labeled video for the Dell drivers. If you are using the on-board graphics, use the Intel Graphics driver. Otherwise, you need the one for the manufacturer of your video card. Note: Dell has the drivers for the NVidia and AMD cards that were installed on some models. If you have upgraded or added a new card, get the drivers from the manufacturer.

I hope this helps.

Dell Optiplex GX620 not recognizing PCIe video cards


One of two things could be doing this:

1: Bad Video Cards
2: Bad PCIe slot(s)

If avaliable, I would test the video cards on a PC with a PCIe slot to verirfy if the cards are good/bad. If they work, your PCIe slot is bad and need to have the motherboard replace to correct.

Good Luck

My tower comes on but i cant see anything on the screen. sometimes it works but most of the time i see nothing except a box that says monitor is working, check pc.

the graphics card in your pc maybe loose. the grapics card is located where you plug your vga/dvi connection in to the back of the tower. If you slide open the town you will see the graphics card in a brown slot beside the white PCI slots. check if it is secure.

Also the vga/dvi cable maybe faulty try a different cable.

It is easy to get the PCI & PCIE stuff mixed up. PCI slots are all white doesn't matter who makes the board. PCIE however is all together different from a PCI slot. The PCIE slot sits fauther away from the back of the computer & so does a AGP. PCIE is a very long card. A PCI is not. The short slot you saw is also a PCIE slots. Not for video but more likely for network card. Most people never use them. Most likely the long slot above the short slot is a PCIE. So you want a card that is like what I'm going to list in this link.|c:1558|&Sort=0&Recs=10
Please list the model number of your Dell & I can tell you exactly what video card you need.
please vote... I'll check back in an hour or two.

Open MY Dell Dimention 3000

look..the graphic card is a miniature board,witha radiator on it,and it is situated perpendicular on to the will see that from its behind there a wire which goes directly to the monitor.thats the recognise part.
in case your computer has no video card,just onboard graphic adapter you have to identify the AGP or the PCIE slot from your mainboard.
this is how you do
look on the mainboard..youll see the processor un the middle..big,with a fan on it(ventilator)
under it..there are some long 10,12 cm long..paralles between them and paralles with the lowest laturaof your computer case..
the fisrt from up...the one which is situated upper is the agp one
I exclude the possibility to be a PCIE slot because your computer is not a today more than sure you have a AGP slot.
ussualy is a brown or red collor..anyway it is different by th eother slots paralel with it. put there the video card and voila...youre done.
however if you had no video before just the integrated on mother board solution,go in bios and desactivate the onboard video.
after that,put the instalation cd or just the ati catalist driver for your new nice agp ati radeon 9600 video board.
with all done,you should have a new board:)
like an advice..I dont recomand you to do this alone..go to a specialised service and let them do it for you,ask them to let you see the job for a next time...but now..if you never did that ..its quite ok to let a specialist hanndle it.,ok?
good luck
oh by the may surf for a while on internet to see some photos with video boards atached on mainboards..
i give you the link whwere I found your dell..It might not have a video board,but only a integrated video on mother board..

good luck
inform me later how it went,ok?bye
