Just built this PC the other day while waiting for my video card to come in. I set everything up and everything was running fine. Got Windows 7 installed then proceeded to install the drivers for the motherboard and SSD. After that I installed the bare minimum I wanted to move on it, chrome, steam, minecraft, origin, adobe reader. Restarted the PC and everything was fine. The last thing I did was I got a update notice for the SSD's firmware since I had an ethernet cable plugged in. So updated the firmware and restarted the PC. Now the PC will not post, no beeps. The 2-digit LED display for error codes normally shoots through a bunch of codes when it posts I assume to check if it's working, but now it just says on "00". Everything turns on and has power, all the HDDs are spinning, my ODD turns on and all of the chassis fans and the cpu are running. So I unplugged all of the HDDs and the SSD thinking the firmware update did something, still no post. Then I removed the RAM, no post, put only 1 stick in, no post, so I just left the RAM out. Then I reconnected the power for the motherboard and CPU and removed all front panel case connections and disconnected all of the case fans, still getting no post but power and running all around. So I figured I would just reseat the cpu and when I took it out I looked at the pins and none of them were bent. After I put it back in, still won't post. So now I'm out of ideas of what the problem could be other than returning the CPU or Mobo.
