I am just started to get these startup errors when booting into XP! I have tryed using system restore with no joy. I have looked round in the registry and found what I think is causing the error! My question is what do i do now!! Can I just delete those lines out of the registry, or will i risk "breaking" my computer? Should I back up before I fiddle?? This is the screenshot of my problem Is it a virus?? Becuase I hav NAV 2002 with all updates!!??
