IT's not the cpu, because code 19 is past the cpu initialization stage and before memory.
Oh thank god. The manual said that code 19 was pre-memory south bridge initialization, so I was under the impression that there was an issue with that portion of the CPU.
Try it with only one memory stick.
I just tried each stick in all four ports to no avail. I'll go check to see if I have any other available RAM that would fit. Thanks for the quick reply.
