reject, mind asking you, i'm having same post codes when i don't have the 12v 4 pin connector from the psu connected. Are you sure it is not the CPU ?
Because i had a working cpu from a friend of mine and i think it died on that motherboard! Well at least it was dead when i send it to him back to test it
My motherboard is new and i've tried two cpu's so far, both with same results and the second cpu which i got today i hope it didn't killed that one as well!
