My PC was running just fine 2 days ago. I shut down that night - wake up in the morning - and it will not turn on. Did absolutely nothing to it. I attempt to turn it on and it just sits lifeless. No fans turn on or lights. Took it apart and tested the PSU using a jumper wire to the black and green wires and the PSU fan powers on just fine. Removed CMOS battery for 5 min. Still nothing. Removed Heat Sink, cleaned off thermal paste, applied new thermal paste and reseated. Still Nothing. I mean there is seriously zero life on my board. I even completely took it out of the case as someone suggested in the case of a short - still no power. I am at a lost for what to do next please? I even tried removing all but 2 slots of Ram making sure to put them in A1 and B1. But nothing! Please can someone help me with a valid next step?

Thanks!

Ok so PSU could still be dead - I do have a multimeter. Is there a way for me to fully test it with that? Or would you just go and get a new PSU?
 
I went out and bought a brand new power supply and hooked it up. Still no power to anything - no fans, lights, nothing. Motherboard is dead isn't it?
Probably.
