Hello. I have and Asus M5a78l-m/USB3 motherboard and until now i had an AMD Phenom II x4 in it, but now i upgraded to AMD Fx 8150 black edition. I checked it, the mb is supporting it, updated the bios, but when i try to start it, the pc powers on, the fans start to spin, but no beeps, the monitor is not activating and the videocard fan always tries to spin, then stops, tries again, stops. What could the problem be? Tried putting back the old cpu, it starts up as normal
 


Try resetting the bios. Also make sure the CPU doesn't have any broken pins on the bottom of it.
