So I woke up today and noticed that my mouse and keyboard were not illuminated which seemed weird. Tower was still powered up and lit up, fans were spinning, water pump was still pumping. Moved my mouse to wake up my monitors and got no response. Looked at my motherboard and noticed its POST LCD was showing Code 00, and the last time I saw that was when my CPU wasn't seated properly so it wasn't being detected. Rebooted my PC and still code 00. Anywhooo, ended up disassembling my pc, removed all components from my MOBO and removed the mobo itself from my tower. Plugged in a different PSU into the wall and plugged in the 24 pin mobo and 8 pin cpu connectors, and still code 00. Reseated the CPU a few times but always code 00. Removed all but 1 stick of ram but still code 00. Tried each of my 4 sticks individually but still got nothing. It just so happens I have a spare (identical) x99 motherboard so tried same steps on that motherboard and still got nothing. Bah. Just opened up a support RMA on the Intel site. CPU is warrantied so hopefully I can do an exchange. I was fighting with my overclock a few weeks ago, so I had actually defaulted most BIOS settings like 2 weeks ago so my CPU was not even overclocked for the past 2 weeks or so, and even my 3200hz ram was only being run at 2166hz. Can't stand being without a PC so luckily I still had my old i7 920 setup with its MOBO/RAM. Had a Radeon 6950 lying around and a spare PSU and an old 160GB Intel SSD and a Razer soundcard so I threw it all together so at least I would haev a working PC until I get this all sorted. You guys think there's anything I forgot to try? Any reason to think the issue might be anything other than a dead CPU ? Sadly I've read that Asus' x99 motherboards seem to of killed a lot of CPU's, my motherboard included. I've been fighting with this f'n mobo since I got it so even though I believe the motherboard isn't dead I do believe it's whats caused the issue. It doesn't seem to get along with my RAM either so overclocking has been a real fight compared to on my i7-920 which always took everything I threw at it like a champ no matter what the f I tried.
