  1. Go into your bios and in the power management settings and make sure that in the " AC Back Function" that you have selected "soft off" This should prevent it from restarting upon the restoration of your power.

  3. Yiou mean PSU or UPS? In case you mean PSU; there are some devices that handle short power fluctuations better than others. I would get a decent UPS from APC for instance. Must not be a big one just to cover fluctuations.

    no i meant UPS (An uninterruptible power supply) the device that peeps and give u power when the electricity goes away
  5. Can you set the sensitivity of your UPS? If so then go for the most sensitive. It seems that your UPS still produces too much output fluctuation for your PSU when the power goes off. You could also buy a better PSU; looks like a cheap one you've got there. What brand is it?
    And what is connected to your UPS? Those batteries are dead pretty fast, and when they are below 1/3 or so juice the output voltage tends to get unstable. You can probably see that if you have a CRT hooked up to it.
  6. And why on earth are we all ranked as noobs here? Shabaa; you had a pretty decent posting score right?
