Do you have a second system to try it in?

Is your power supply sufficient?

X79 and an R9 390 on 550w seems a little tight but even then you should be able to boot

I don't know what's wrong with my pc,it boot successfully with my 7950,but my 7950 has some problems,so I bought an R9 390

Reset the BIOS.
Goto BIOS (maybe with another Card), look for PCIe Gen and set it to Gen 2.

 

 

The X79 Plattform wasn't really designed for PCIe 3.0, that was more of an afterthought and introduced with the 4820 and 4900 series aka Ivy-E.

Sandy Bridge-E does not have official PCIe 3.0 Support. Inofficially it works with some cards but not all (causes Problems with nVidia Kepler Series Cards)...
