I'm having some problems with the motherboard where the OS will start only when I set the BIOS to 2 or 3 cores of the i7 2700k CPU. Cpu tested fine using Intel utility. I tried updating the BIOS but I can only flush it to 2303 which is 3 generations old. Any newer shows as "image invalid". Possibly it's because the BIOS is for rev.3 of that mobo but then apparently when the mobo is labeled as mine as 1.01 it doesn't necessarily means it's not the 3.0. Anyway Asus's website doesn't have a link for 1.01 so I'm not sure what to do. Tried contacting ASUS but so far no call back as you cannot talk to their support direct. On-line chat doesn't work either.
