Today my power supply went out on my PC and I replaced it. I installed the new one and powered it up. I have all drives and fans up and running on the MB but the system will not do the POST and I get no beep. There is also no video coming on my monitor. I looked over the MB for blow capacitors, scorch marks, etc and nothing. There was no lightening strike and no surge here at my home when it happened. The PC was in hibernate mode, I went to wiggle the mouse to bring it out of it, and then the PC just shut off. Any ideas before I go pay for a technician to look at it? Thanks.
