Can you please confirm that your notebook have nVidia Go 6150 graphics ?
You can do so by downloading GPUZ from here and running it:http://www.techpowerup.com/gpuz/
Which OS you are using?
I was able to find XP (x86) drivers for this graphics chip:http://h10025.www1.hp.com/ewfrf/wc/genericSoftwareDownloadIndex?cc=us&lc=en&dlc=en&softwareitem=ob-43453-1
Note: Before installing these drivers please do create a 'Restore Point', so in case there is any issue, you can reboot in safe mode and uninstall the driver.
