I continue to struggle in getting one of my latest builds working, and this time I have a feeling that the CPU could be dead. It is a brand-new AMD 1090T six-core processor that I bought from Newegg last month. Problem is I switched from a seemingly broken MSI 790FX-GD70 to a brand new ASRock 890GX-Pro3, and alas it doesn't work either. When the system is turned on, the debug LED displays a series of fast numerical codes and then stops at "00" with no (onboard) video or other signs of life; does NOT POST. I have tried removing all but one memory module, removing graphics cards and clearing CMOS several times. I am using a 500w Corsair power supply. This is a very similar issue I was having on the MSI board, where the debug LED would sit at "FF" and would not POST either. The only real difference is that this ASR board is equipped with UEFI BIOS but I haven't seen or have been able to actually use it at all. This is starting to lead me to the conclusion that the processor is dead, which has never happened to me before, but perhaps I need to get it replaced. Any thoughts?
