Default Dell PC blinking yellow


Dell Optiplex 755 is not boot up and flashing yellow only not power go through MB. Google search is all saying there is problem either on PSU and the mother board. I connected other PSU on Dell and found no problem and I am using that PSU on Dell PC now. I also connected the Dell PSU on other computer and found no problem either. So basically Dell PSU and MB are Ok. Why the Dell PSU is not only working on Dell PC?
