I have an HP DC-5100 that immediately shuts itself off when I boot it up. Well, not immediately, it starts up Windows XP SP3. You get the splash screen, it acts as if its loading, then you get the "saving settings" and system is shutting down" message and it turns. Its an orderly shutdown. No error messages or beeps.
It was running when I went over to look at it. Shut it down to replace the UPS and then it started doing this. Since I was running out of time, I brought it home with me. Funny thing is it now boots up perfectly normal.
Could hardware attached cause this? Any help would would be GREATLY APPRECIATED!
