Optiplex 760 diagnostic lights 2 3 4 blinking and solid amber power light

Question

I have an optiplex 760 mini tower with the diagnostic lights 2 3 4 blinking and solid amber power light. Ive read that this could be a motherboard or bios failure and I might need a new board. Is there any way I can avoid buy ing a new motherboard?

I think you just need to adjust your Hard Drive's Cables.I also had this problem once.
