Very Strange because Error 797 is specifically a driver issue. It usto happen all the time with Windows 2000 and every time removing it through Device Manager and installing the latest driver would do it. I have also seen it about 15 times on PC's running XP since XP came out. And was able to resolve it the same way. For your issue I won't be able to resolve it through this forum a more hands on approach is needed. My apologies.
