  2. Make sure the 8 PIN CPU POWER , AND 24 PIN power connections are properly seated.
  3. ASUS tech support doesn't even help you, they just keep pushing you for an RMA. BUT THE REAL PROBLEM FOR ALL IS the 3 pin connector for the cpu . That's the culprit, You need to NEVER connect to the cpu power 3 pin female connector to the mobo 3 pin cpu fan male connector . You have to use the 3 pin female connector from the CPU on the 4 pin male connector just to the right of it on the MOBO called the cpu fan optional, it is a 4 pin male, but you use the 3 pin female cpu connector there and the embedded slot that places it in the right direction IS USED leaving 1 pin unused> so spread the word...the 3 pin male connector on the sabertooth FX990 is useless.
  4. I had the same problem: ASUS Sabretooth 990FX with AMD-FX6300, 16 GB DDR3 RAM. RED CPU always on, and no signs of life except for LED indicator that power was on. Got a power supply checker...all OK, got a MB checker...no POST. Pulled CPU and replaced with another from Amazon (did I mention the great customer service? Replaced the CPU chip after I explained. With second CPU, board booted, red CPU LED went out, and I in the BIOS Setup Screens. Looked closely at first CPU--> bent pins in one corner (very hard for old eyes to see). So the red CPU LED being always on meant something that was useful.
