I have bought an ASUS P7P55D-E Premium motherboard and a core I7 875k cpu - I cant even start the Bios to have a look - only a red light on the motherboard telling me something is not right with the cpu. Everything else starts, fans, harddisks and so on, but not the bios. And the cpu seems to fit right.
I have an idea that it might be because the bios is too old and therefor needs updgraing.
I havent got another older LGA 1156 cpu and have no possibility getting one but are stuck with the new one
Is there a way to upgrade the bios without cpu or what else can I do?
you need to have a working CPU to update the BIOS (without a CPU, the system cant really do anything).
i doubt it would be a BIOS issue though, since the 875k should work in any 1156 board without an update. you could try borrowing a CPU from someone else, but i would be more inclined to believe either the CPU or Mobo is faulty.
