there is a lot of power outages where i live so i have a ups, but last night it seems that the ups wasn't enough and there was no power for a long time. in the morning i woke up the pc was off i turned it on and it immediately turned back off, i pushed the power button again the pc turned on but no post nothing on screen at all, turned it off that back on and it booted normally. what could be causing this?
 
Solution
sometimes the powersupply needs a bit of time to charge up, after a power outage I always have to double boot in order for my computer to start.


but the psu was plugged in a long time before i boot
