I recently purchased an ASUS M5A99FX Pro R2.0 and an FX 6300-six core processor. I am having troubles booting with this new processor and motherboard together. I tried the new CPU with my old motherboard and it worked. Old CPU and new motherboard worked. New CPU and new motherboard don't work. I updated the BIOS to the most recent version as well as the version that was released when the CPU was supposedly supported. I am running out of ideas and ASUS isn't responding very quickly to my question about this. Anyone have ideas as to why this is happening?
