  1. What is an AVR first?

    -Always put the blame on you first, then on the hardware, UNLESS YOU HAVE A PROBLEM WITH A MSI BOARD !!!
  2. the problem is that the computer will boots-up or it will turned on(power on) without pushing the power button on the computer.meaning once I switch on the AVR the computer will boot up and will start winxp.i'm not even touching the power button on the computer.
  3. AVR-automatic voltage regulator, just like a UPS-uninterrupted power supply
  4. Sounds like BIOS is set to resume after power failure.

  5. Not sure but I think my computer does this too when plugging it into the wall and im sure its not set to resume after power failure. I think this is teh way PSUs are designed? It sees it has power so internal circuits switch on. The only way to keep my computer off is if I dont use an external switch, meaning that the power supply always has power given to it. That way it can detect when you press the power button on the front of the case.

  6. Most of the BIOS settings I've seen for newer boards have 3 settings available for how to act after a power failure: Stay Off, Turn On, or Last State. Last State is supposed to remember whether the system was powered or not. I use Stay Off for my home PC, but if I were running a web server I'd set it to Last State.
