The MoBo + old CPU and all other hardware worked just fine.
I updated the BIOS with that setup as recc'd by the instructions with the new CPU.
I re-booted and all worked fine with the updated BIOS + old CPU.
I installed the new CPU - AMD FX-6100 and now nothing. No POST, blank monitor, fans come on but no booting.
I took out the new CPU, reinstalled the old CPU - it all works fine.
Reinstalled the new CPU and back to nothing (except fans).
I've seen reviews about some Asus boards that despite being AM3+ boards (designed for FX processors) they have not had "out of the box" support for Bulldozers, I would recommend contacting Asus for support.
