Do I need to replace my graphics card

[spmctm]

HP Pavilion Desktop - 550-127c 

4 months out of Warranty  it appears the color yellow is not being rendered, anything on the monitor that is supposed to look yellow now appears as a light grayish green color.

I have updated the chip set and video drivers

I have tried 2 other known good VGA cables, I have tried different monitors, and proven the current monitor good on a separate system as well as the VGA Cable

I tested using the HDMI output from the video card as well and got the same result

I do not know what else it could be other than the graphics card failing

this is an integrated graphics card on on the MB, I do not wish to replace the MB if I don't have to

there appears to be an available slot , can I purchase a standalone graphics card ?

any suggestions on anything else I can try or what model graphics card I should purchase

I do not do any gaming or video processing so I don't need anything high powered just something decent and reliable

You have to use external card now but your machine only has 180W PSU therefore you can use GeForce GT 730 (available on some machines - pre-installed option) or other AMD card with similar wattage.

@spmctm , welcome to the forum.

@banhien, gave you some good advice.  However, I suggest that you try calibrating your monitor.  The symptoms that you described could be a problem with the monitor.

well that did not work

new card installed and same issue,  new card has a dvi and a vga output so now I can see the same color issue, ( no yellow) on 2 different displays simultaneously further proving there is not an issue with the monitor(s) or cables

so it has got to be the MB right

Hi !

This is a weird behaviour which you are facing to and the diagnosis steps you completed are very helpful. Without you having already checked it, I would have suspected a faulty pin in the VGA link.

Give a try to another operating system, try to boot the machine from a Live CD and check that the yellow colour is absent too. I do not believe too much your problem might be OS related, with some malware under the hook, but it might worth to test it, too.

Regards.
