I built a computer yesterday! It does not post. It boots, all the fans go to maximum, then it settles down. As it first comes on the LED error indicator on the AsusRock motherboard shows error 15, then immediately the error changes to 53 and stays there. The computer reboots every minute or so. There is never any output to the monitor.
Both 15 and 53 are the same kind of error, according to the manual. Error 53 indicates "Problem related to memory. Please re-install the CPU and memory then clear CMOS. If the problem still exists, please install only one memory module or try using other memory modules."
The build below excludes a 2010 model DVD-RW optical drive that I took from my old computer. I will add its details as soon as I am in a position to pull it out and look at it.

What I've done:
What I have not done:
I really wanted this to be a memory problem, but it appears to me, an ill-informed layman, that the problem lies in the processor or motherboard. I'm not sure what else to try beyond exchanging either of them.
Then again, I am not an expert. I am hoping you folks have a better idea of what's going on here and other ways to determine whether it's the motherboard or processor (or memory) causing the problem. Maybe we can even fix it without resorting to an RMA! I will take whatever advice you give and answer any questions.
I will edit this post and add a post on this thread tonight once I've tested the old memory stick on the new system.
EDIT: I tried a stick of working RAM from my old computer - in every slot, just to be sure. The boot sequence and error numbers were exactly the same.

What I've done:
■ I reviewed previous similar problems posted on this forum, noting the most common factor seemed to be bent pins.
■ I have tried booting with a single stick of RAM. I have tried each stick in every slot, clearing CMOS between each boot.
■ I have removed the pump from atop the processor, cleaned each with 99% isopropyl alcohol, and then removed the CPU. The CPU showed no signs of damage under magnifying glass.
■ I examined the socket on the motherboard, also with magnifying glass. No pins appear bent.
■ To confirm, I enlisted someone else to look over the socket thoroughly after telling them what to look for. They confirmed that none of the pins appeared bent.
■ I rested the CPU on the socket all four ways, confirming that it only "dropped" into place in one position - the same position I first installed it. I again pulled the little lever that secures it in place (sorry, I don't know the technical term for it).
■ I reapplied thermal paste (a N1H1, I believe), replaced the cooler pump atop the socket, rewired everything I had moved out of the way, cleared CMOS, and plugged in the computer. I booted it. It followed the same Error 15 -> Error 53 pattern as before.
■ I removed all the RAM (after unplugging the system), then booted it. The same error sequence resulted: Error 15 then Error 53.
■ I confirmed that the motherboard supports this CPU on the ASUS website (it does).
What I have not done:
■ Take a stick of memory from the old computer and try booting with it in each slot, clearing CMOS between each boot. I plan to do this tonight.
■ Disassemble the system and breadboard it.
