Hello. I built a computer about a year and a half ago. It was working fine at the end of this year. I took it apart to move and when I put it back together exactly the way I took it apart, the motherboard would not post and gets stuck with the cpu led staying on red. There is no video output and no beep diagnostics from the speaker. These are the specs:
Asus Sabertooth x79 mobo
Intel Core i7-3930K
Corsair CWCH80 Hydro H80 CPU Liquid Cooler
ThermalTake Overseer RX-I Full Tower
ThermalTake TR2 600W / LSP Ultra 750 W Power supplies (see below)
Kingston 1600Mhz DDR3 RAM (x4)
OCZ 240 GB Solid State Drive
When I first started having the problem, I figured the problem was the motherboard. I was running BIOS 2002. First I flashed a version of the latest BIOS (4608), which seemed to work fine (blue BIOS flash LED blinked for a while then went out, consistent with a successful flash). Same issue. I then tried to flash the original BIOS back since I knew that worked (2002). It seemed to flash successfully (from what I understand, from 2002 onward, you don't need to use the cap converter or Asus renamer tool). Still didn't work. So I called Asus and they did an RMA of the motherboard. New motherboard came. Same issue. So I figured it was the CPU since that was the light that was on. So Intel RMA'd me a new CPU. Same issue occured. So maybe it was the power supply. The one I was using was the LSP Ultra. So I bought the ThermalTake TR2 600W and installed that. Same issue. I've reseated the CPU countless times and checked the stand-offs numerous times. I tried the new (supposedly verified) CPU as it came and with the newest BIOS flashed (seemingly successfully) in there. The BIOS that I'm using lists my CPU as supported. I've tried booting the motherboard outside of the case with 1 stick of ram and essentially no connections. I am about at the end of my rope here and still have no idea what could be causing this since I've systematically replaced everything I could think to replace. Any ideas what could be up?
