Hiya morpheus and all
I'm no expert, but it appears to be, like everyone has already said, a graphics issue. That card also appears to be quite old now, I've never used a Quadro card, but that appears to be an older 4x AGP card and that may be the cause of your problems.
I usually play around with graphics settings if I have issues, just to see where that takes me.....doesn't always address the problem, but sometimes works
I'm not entirely sure if the problem is fixable with a card that is running on the older 4x AGP setup, you may need to upgrade your graphics card unfortunately.
The range of Quadro4 XGL cards is available
here, just to show you the specs
Regards.
DJM.
Edit: Just ran a quick search on Amazon and found this:
Date first available at Amazon.com: July 24, 2002, should give you some idea of age
