Take the cpu and reseat it. - Done , didnt help
Check for bent or broken pins - done , no pins borken or bent one either of MoBo

Check for thermalpaste on the bottom of the cpu - none

Try a different psu(just use 24 pin and 8 pin) I am using a 24 pin and 8 pin ( OCZ 850W =) ) , and so far i worked well on my second rig , that should require more W power than this one ( thanks to Phenom and two 4850 ) .
clearing the cmos with the battery out - done , didnt help.
Well I've sended my Q9550 back for replacement , maybe they will sand me back an E0 stepping
