ASUS Sabertooth 990FX R2.0 Boot Issues

Hey, I just tried to power up my computer for the first time, since building it. The Boot Device LED is always on, it does not allow me to get to bios. Not sure as to what im supposed to do.

Here is my parts:
Mobo:ASUS Sabertooth 990FX R2.0
CPU: AMD fx 8320
GPU: GeForce GTX 750
RAM: Corsair 2x4gb 2000 ddr3
HDD: 1TB Seagate

Any suggestions?

  1. what PSU do you have? Have you double checked to make sure all connections are made properly?
  2. I have a Coolmaster 650W, and yes. I double checked it just to make sure.

    Make sure the RAM is seated properly... Does your computer beep at all?
  4. I have your same specs and had the same problem. a BIOS update using the USB bios flashback feature solved this case for me. stock bios on my board didn't support 8 core cpus from the get-go
