today i check voltage capacitors in daughterboard rev b with multimeter and
the result is 4,83v in tree big capacitors in daughterborad , 4,92 in molex hdd
this is good ? or too low?

In my experience 4.92v is right on the edge of reliable operation.I am not sure that is your problem,but i suspect it might be.4.83 seems pretty low on the backpane,you might clean the riser board contacts and the slot on the motherboard to see if it helps some.I think your psu is marginal though.
