You haven't said which OS you're using, two oaks, but it sounds like Win95 or 98. That shutdown file is called either Logos.sys or Logow.sys, I can't remember which, it's been a while. Do a search of your hard drive see if you can find it. But why are you still shutting down that way, two oaks? If you go to Control Panel > Power Options > APM tab and tick "Enable advanced power management support", click Apply and OK, the computer will shut itself off completely without you having to press the off button. That is if your motherboard supports that option.
