I recently moved into a older home. I plugged in my desktop and it powered up but never POSTed.
Going through the defacto moves I did all this:
Reseated RAM
Unplugged all peripherals.
Ran the comp with 1 stick of ram.
Swapped out RAM in every configuration to test them all.
Changed between 4 different hard drives.
Nothing.
Changed out the PSU.
Swapped the MoBo.
Swapped the CPU.
Nothing.
Changed keyboards, monitors and mice.
Nothing.
So this has been going on for a month.
I recently got another computer from a friend who upgraded. It worked fine before.
Plugged it in and same issue.
Looking at my laptop power it says "100-240V/2A"
my PSU ( the lowest one out of 3) says "120-160V/10A - 200-240V/5A"
So comparing it, it appears the laptop needs a much lowers V-A ratio.
What comes on:
PSU
Mouse
Keyboard (flashes and goes blank)
Monitor (but no signal)
Fans
HDDs
Could it be that my house is delivering less than the needed power to start the CPU?
