Hi in the recent weeks i have been having brief 1 sec power outages,which always makes my pc shut down and immediately turn back on. The only setting i could find in the bios is under APM/Restore AC Power Loss set to power off. As a test i tried all settings (power on,last state) and simulating a 1 sec power loss by switching the psu off and immediately back on again. Still same behavior! I am completely lost as to what to do to make my pc stay off in such situations. What else could be causing this behavior i am totally confused. BTW my PSU is only 10 months old.
