Are all the stand offs installed correctly on the mb?Hey everyone. I’m rebuilding my computer and I’m having a strange issue with it. It won’t turn on at all when the cooler is seated on the processor. I have an AMD FX 9590 processor, an Asus M5A78L mobo, and a Scythe Katana 4 cooler. It doesn’t matter if the cooler is plugged in or not, if it’s sitting on top of the CPU it won’t power up at all. Not a blip, no lights, it’s just a brick. Any ideas what in the world could be causing this and how to fix it?
Perhaps micro fractures? I'm suspecting the weight of the cooler.
Is it pushing hard on one or more of the RAM sticks? I had that problem with this Lenovo M82 SFF rig, it has four DDR3 DIMM sockets, but when I filled all four with GSKill 4x2GB DDR3 sticks from a kit, the sideways pressure from the CPU heatsink, wouldn't allow the DIMM to seat properly. The OEM system was designed for RAM that was thinner, without heatsinks/heat-spreaders. So I compromised. I used the original two "naked" DIMMs, in the closest slot and the third slot, and then I populated the other two with the GSKill RAM that I had. Thankfully, they were all compatible, AFAIK.
It wouldn't boot when the RAM stick was getting "squeezed" from the side.
if you have micro fractures, replacing the mb is the only real solution.Can you give me a good, lighter weight cooler i can try?

if you're having the same issue with two different mb and cpu, it's a problem with assembly. The wrong header being used for the cooler perhaps?I’ve already replaced both the mobo and the CPU. It still doesn’t boot.

It won't boot if there's nothing plugged into the header. You said if you unplug the CPU, it will boot. I'm having trouble understanding what you mean because without a CPU, it absolutely will NOT boot.
