I need tech people.
Dad tried to build my mom a new PC, couldn't get it to work. He has tried a different mobo, psu, ram, even so far as to get a different cpu. He couldn't get it, asked me to give it a shot.
Plugged the RAM and PSU in my machine, booted up fine, no errors testing RAM. Those are good, HDD is good (he used my SSD with windows 7, a different HDD with windows 7, and a spare HDD with linux as random testers in the borked machine as well). Anywho, I tested everything I could sans the CPU and mobo because I don't have an 1150 socket (wife's PC is ivy bridge, mine is an AMD).
Problem I ran into:
Soon as you switch on the PSU, it draws power and fans and ***turn on, without ever hitting the power button on the case. No post, no screens, nothing... just power to everything (can hear the HDDs whir up).
Did this with different combinations of parts. I completely pulled the case plugs out, made sure nothing is shorting the pins to make it auto-boot. All looks good to the eye, but still just turns on. My guess is shitty mobo, any other theories?
CPU is an i7-4790, mobo is an ECS B85H3-M. Dad replaced both through newegg with the same parts. Apparently it was doing the same thing on the other mobo, he traded mobo, still did it, traded CPUs, still does it.
