ASUS Z87 -A UEFI/BIOS stopped working

I just bought a new i7 4770k and an Asus z87 -a and 32 GB of Patriot 2133 mhz RAM to upgrade my current build.


Current Build:


New Build:



I installed my motherboard in my case, added RAM and CPU then connected everything with my PSU. Started. POST had no problems.

Next I pressed F2 to enter UEFI and clicked on advanced settings... Suddenly a freeze occured when I scrolled down a bit then I turned off the computer after waiting 2-3 minutes.

Then I tried turning it on to notice:



So I cleared CMOS by following the steps in the manual but it's still not working. And yes I checked different RAM, cpu for bent pins. PSU is working on my other build. It doesn't look like a PSU/CPU/RAM problem.

  1. If starting the board, only CPU and CPU fan installed, both 24 and 8 pin power cables connected, are you still getting the CPU red error? Is the CPU fan spinning when starting the board?
  2. Have you tried to put ur RAM memory on AUTO set speed then see if will work ,if still problem presist ,remove CPU try to put him back clean and good not to much force,check if the CPU fan works =IMMPORTANT,see all cables that are connected to MB are connected doog,see if u missing something ok..then tell me more...

    Now the CPU fan is spinning, CPU LED is flashing and because there is no RAM the DRAM LED is solid red.

    I cannot access UEFI/BIOS because it's not even starting. I can't set my RAM Memory on auto. No signal.

    Insert single RAM stick and test again.

    I tried that before

    CPU + CPU Fan + 1 RAM (A1 to B2) = CPU Led and DRAM Led flashing
    CPU + No CPU Fan + 1 RAM (A1 to B2) = CPU Led solid and DRAM Led flashing
    CPU + No CPU Fan + No RAM (A1 to B2) = CPU Led and DRAM Led solid
    CPU + CPU Fan + No RAM (A1 to B2) = CPU Led flashing and DRAM Led solid

    Same results with another PSU.

    I read blinking may indicate a short, but I can't imagine how this could happen.

    Try testing the components at a local shop. Or RMA the board and the CPU.

    Seems like the motherboard is faulty. I will RMA it then.
