Flicker of power, then dead sounds like dead PSU or a
short somewhere.
Remove everything attached to mobo except power &
video card and work
from there was always my method. This includes the
front panel cables,
you can simply short the mobo power switch jumper with
a metal object to
power on.
Of course the obligatory reseat the video card, RAM, &
PSU connector
then try an alternate PSU before going whole hog &
removing the mobo
from case.
If you have a functional second pc there is always the
"swap until it
fails" method which is way more time consuming but
effective.
