well i found out what happened, seems that the r11 and r12 resistors both opened up, which opened the 24 volt feed to the 5 volt regulator chip. since these were both 2.2 ohm resistors in parallel, i jumped them out and all is well. using the card for a test rig, so it is not going to be a problem leaving the resistors jumped while i play around with my test set up. my wife now tells me the cat was climbing on my desk, maybe the damn cat did it. ha ha
