amd phenomII 955 processor (Black edition 3.2Ghz)

MSI R5570 1 gb graphic card
psu coolermaster 600W

when i connect all this and try to start my pc there is one short beep and no post,no activity in hdd light. keyboard light just blinked one time
i tried my psu on other system it works fine,
i check the cpu ,its getting warm on 890gxm-g65 but not on my new msi 990FXA-GD65....
i removed my video card, no boot either..
also replaced the motherboard with new MSI 990FXA-GD65. no success...:(
now i'm stuck....

motherboard LED indicate that cpu is in 2 phase power...

anyone have a clue....

thanks for any help i can get....
