    But the monitor does work in another computer?
    Some graphics cards will not work with limited memory... I would be sure you have 1 Gb, and preferable 2 GB, depending on what the new graphics card might be.
    But we can assume you have thoroughly gone over the checklist that came with the video graphics card? And you installed the drivers from the enclosed disk?
    Does the computer still work with the old video graphics card?
    Do you have any red or yellow flags in the Device Manager?

    Your monitor is working with a different card on the same mobo, right? If so, your card may not be working.

    However, you could try your HD4850 on another machine to see if it runs.
