I am using NVIDIA GeForce 8400 GS @ 512 mb graphics card in my windows server 2003 32 bit. I have installed the driver from the cd that came along with the graphics card. It copies the driver and when the setup is complete i frequently get the message which says to accelerate the hardware acceleration to full. When i did so my pc gets restarted. Then i will unable to boot and computer never gets started. I have to formate it once again. when i look in services it shows that service is starting for nvidia display driver but it never gets started. Another problem is i am unable to play dvd or any video. i can hear the audio but piture is gone. I have searched the driver from nvidia site but there is no driver of nvidia gf 8400 gs @ 512 mb for windows server 2003 32 bit.
