WHEN PLUGGING IN HEADPHONES OR SPEAKERS ON NEW DESKTOP I GET A PERSONS VOICE ACTUALY SAYING "DANGER" REPEATADLEY NEVER HAVE I HAVE HEARD OF THIS PROBLEM NOR HAVE THE MAKERS SUPPORT TEAM (REALTEK ON A GIGABYTE BOARD) IT HAS ALWAYS DONE THIS SINCE NEW ABOUT 3 WEEKS HAS ANYBODY EVERHEARD OF THIS I HAVE CHECKED FOR VIRUS

This sounds like a motherboard issue - maybe the board is having issues? My guess is that the CPU is overheating - does the computer shut down on its own too? Definitely sounds like an overheat issue.
