Display failure

I have a Windows 2000 server. I get a blue screen on boot with the error “Stop 0x000000B4 The video driver failed to initialize” I have tried booting in safe mode and still continue to get this problem. I have replaced the VGA adapter and still havethe same problem. I have Oracle loaded on this server and it does not have a backup device installed yet. Is there anyway to recover / repair this server keeping all my settings intact. I have disables the LPT port. Due to remote location and skillsa reinstall of Oracle is not possible.
