Sabertooth 990FX R2.0 with AMD FX 8350 Processor problem

I built my friend a computer this weekend and put everything together and checked, double checked and then triple checked everything was connected.

I then plug it all in and start it up, The PSU powers on and the motherboard starts up, but we get no signal for the monitor and keyboard/mouse.

I've gone through the step by step guide here to check if everything is correct and it is, and i've searched the web a little bit to see what the problem could be and the only logical answer i could find was that the AMD FX8350 processor did not work with that Sabertooth 990FX motherboard because you needed a updated bios or something?

Can this be the problem why i'm not getting a signal to the monitor, mouse etc ?

The set up is as following

ASUS Sabertooth 990FX R2.0, Socket-AM3+
AMD FX-8350 8-Core Processor
Corsair DDR3 16GB 1600MHz Low Profile
XFX ProSeries XXX Edition 750W PSU
Nvidia Geforce 580 GTX Graphics card.
Seagate Barracuda® 1TB

I should mention i tried with both his monitor and mine which i'm using now.

Thank you in advance

  1. If everything is really connected, try to push on button and hold for 30-60 seconds. It will restart BIOS.
  2. Best answer
    You need an updated bios for that setup, at least ver. 1006

    Luckily that mobo's BIOS can be flashed without a working CPU.

    (assuming you are running win7 64, just select different from drop down if not)

    Stick the BIOS in the top level of a USB stick, plug into your machine and press the BIOS Flashback button for 3 seconds with the power supply connected.

    It is a problem ASUS has with AMD boards - I have this board and use the AMD 3.4gig FX965 processor - I get the CPU LED light red and am awaiting my 3rd board from ASUS - 5 weeks and counting of dealing with them. My next board will not be with them or ASROCK (ASUS owned)
  5. Have you Fixed the Problem yet ? I do have the same Rig (as seen below) and no bios flash needed or anything else, it just worked so if it didnt work out just tell me.
