pc suddenly won't start?

[KabuTheFox]

had this build for almost 2 years now. MB is the msi x99a sli plus and PSU is a evga supernova g2 750w. only thing recently switched out was the ram, but that was months ago at this point.

•  

i had turned it off via the switch on the psu earlier today as i was expecting a storm, however i did not unplug it from the wall. i do not believe one rolled through however as its been sunny all day. there was one last night but it didnt cause any outages.

when i went to turn the switch back on and power the pc back on nothing happened, just a small blue light on the MB and thats it.

the light that is on is circled, below

•  

what happened, and is there anything i can do?

tried;

reseating ram

resecuring cables on the mb

switch the bios switch between A and B

clearing the cmos with the cmos button

switching outlets

switching power cables

u pretty much need a multi meter to measure the output of the psu ,also check for shorts & zapped traces ( continuity check ) on the board .

do an eye check of the socket pins too , something could be bent - shorted
