Well it is too bad to see it failed. Here we have a couple of more steps to do due to this situation.
I would like you to try with the latest BIOS update and if you already have it try to reinstall it on your system. It is a long shoot but the system may have lost the microcode for the processor and may be causing conflicts with it (not very common at all but possible).
In case the issue persist, I recommend you contacting Asus for them to replace the processor.
