Invalid configuration information - please run setup dell 740

I get this message, and I'm wondering why?
And what can be done?

Is this message caused by PSU problems?

PS: The computer is a Dell Optiplex 740.

  1. hmm, not likely a PSU issue.
    Has anything changed recently?
    Are you able to get into your bios (and reset to default)?
  2. Sounds more like the cmos has corrupted and it has reset to safe defaults.

    Have you replaced the cmos battery and gone in to bios and set everything up?
