m6vlq mobo

we just bought 4 of these mobos as replacements for failed parts

all four will not post

i get no video no beep


swapped ram
swapped cpu
swapped psu

disconnected all components, pulled from case, still dont work

any clues?

im absolutley boggled

anybody?
anything?

The only thing I can think of other than dead boards is possibly cmos jumper. Some companies ship motherboards with the jumper in the clear mode instead of normal operation mode.

i checked
double checked
and then checked again on all four

that is not the issue

but ty for replying
