Need to fix yellowish tint from GEFORCE FX5200 on Dell GX280 --no problem with monitor

l
I have a Dell Optiplex GX280. It came with an on-board, Intel video card. I disabled Intel video card, and added a Nvidia  GEFORCE FX 5200 in one of the slots. I use windows XP Pro.

I downloaded the latest Nvidia drivers (installed themand then thinking I might have a corrupted download, I  un-installed these drivers, re-downloaded them, and then installed them again.

I tested several monitors, and know the monitor is irrelevant to the problem. (The old monitor works fine with the on-board Intel drivers; and the other monitors I tested work fine with different computers. Therefore, the monitor is NOT the problem.

The PROBLEM is that my desktop, programs and the Internet all show a a yellow tint (instead of white). In using the desktop control panel Nvidia supplies, I noticed I can adjust red and green, but canno0t change blue. Also , in selecting a color desktop in Windows XP, I cannot get a true, blue color from the regular suggested colors, and even in advanced, I cannot make a regular blue.

Using the Nvidia supplied software, I have tweaked brightness, contrast, and color adjustments. I even tried the warm/cold adjustments on the monitor.

Sometimes, playing with the adjustments I can minimize the yellow  tint and glarebut a few hors later, the strong tint returns.

I tried the  Nvidia  GEFORCE FX 5200 on a different computer, and it works fine.  

Using Google, I have seen references to upgrading bios, but I saw no new bios on dell's support. My computer's  bios are dated 2006.

I believe that I need to find a way to make this video card work in this computer, but cannot seem to find the problem. Maybe I do need to flash or upgrade bios, but if so, I will need some guidance.

Is this when you are playing games?  Take a look at these articles:

Don't know if it's related.

No---The tint is universal. It is not extreme, and seems to be an absence of blue, aklthough things like  the Internet Explorer icon in the taskbar  is the correct color.
Is it an AGP card?  I'm assuming it is, but is it the prescribed AGP version (2X, 4X, 8X) for that motherboard?  I can definitely help you with loading the new BIOS from DELL.
Please tell me how I can tell if it is an AGP card, and if it is the prescribed version.

By way oif background, the card was bought in a computer superstore to upgrade a different computer my son used. In other words, it is an off-the-shelf, Nvidia  GEFORCE FX 5200 card, and not one that came loaded by a manufacturer of a desktop.

Will flashing the bios be likely to do any good?

it is a PCI Express card - NOT AGP
can you test the card on another PC? it may just be a bad card
The card works fine in an HP desktop. It is not the card.

I want to mention again that using the Nvidia software, I cannot directly adjust the blue color the same way I can adjust the red and green. Also, on the Windows desltop, where you right click on desktop properties and cvan change the appearance, the blue colors all look very dark or with a green shading. I cannot make the desktop color royal blue, although that is the color I generally like to use for my desktops.

I think this may be a meaningful clue (since I think blue is related to getting the white color that looks yellow on my Dell.
if it is not the card, or the software, there is not much left : cables, motherboard ?
whaat do you think about flashing the video card related  bios, a procedure I saw when I googled the issue of "yellow screen on monitor"? How can I find out if my computer has bios that need flashing for the video card?
Apparently that is not the card that the computer originally shipped with.  Here is the place you can go to find out if any of the original hardware needs to have drivers, or firmware updates:

since it is a separate card, i doubt flashing the bios will help.
since there are no new bios, you can try flashing to an older version.
i think it is rather a motherboard problem, or even cpu problem.
Hi Focusers - I'm not sure if you have one to hand but have you tried a different graphics card in the PCI slot that you're using for the NVidia?

I know that you have sent the computer back, but did you try changing the color settings or temperature in the nvidia software.  I deal with graphic art and use a calibrator to calibrate my monitors, but there are some programs out there (adobe gamma?) that will get you in the ball part for free.
I tried every possible configuration both using the software, and on the moniitor, but nothing worked. I believe that Dell will be replacing the computer, based on my last email exchange with it.
