Random PC Shut Down While Gaming In Crossfire?

Hi AMD Community!

                    I recently upgraded my old AMD FX-8350 Dino....sad to see her go but needed to know if AMD got the goods back on track. Any ways I have been experiencing random shut downs while gaming in Crossfire. I haven't  had it shut down like watching movies or youtube clips.. just in Crossfire games ) ( more so in Open GL games it just crashes even faster then in Dx games. These are my specifications. Any input would be most appreciated   and so many thank yous in advance......
