Looks like you're not using the best resolution for your display. Use the nVidia control panel in Windows and reset the resolution to the native resolution of your Mac.

Remember - you must set it while in Windows, not from Snow Leopard.

pls clarify whr can i reset nVidia,pls guide me
i've got a nVidia nView Desktop Manager in VMware fusion - bootcamp - windows xp control panel,that doesnt respond if i click on it,is it the one ?
ultimately i wanna use both mac and windows xp using VMware Fusion

In Fusion, you're not using the nVidia device directly, you are using a virtual graphics adapter in your virtual machine. That's why it won't work under Fusion. From within Windows in Fusion, go the the Control Panel and Display section and set the resolution in there.

If you also have Windows installed under Boot Camp, it should work when you reboot into Windows from Control Panel as well, under the nVidia application or the Display box either way.

Why do you guys still use XP? You know that it's ancient, right?

yea it works in windows if i directly boot into windows,without using fusion.
but my job needs both platforms at a time,Catia V5 (cad software) works only in windows platform and the office works in mac.so i need to use fusion to work in both at a time.i tried to change the display settings in Vmware fusion - windows but it didnt work.
is thr any way i can allocate more graphics memory to virtual graphics adapter in my virtual machine ?
