Asus p9x79 pro Q-Code 19 ? Can you Help me ? Whats the problem ?

I had the same problem start a few days ago on my Asus p8z68 deluxe/gen3 motherboard after 2.5 years of flawless running. When you turn on the machine the cpu led light comes on and the q-code displays 19. The manual states that it is setting some PCH parameters. Anyway, I figured out that gently wiggling the memory modules side to side a few times and making sure they are properly seated did the trick. It only seems to happen to me when the machine is cold so I fear that it might be a bad solder joint or trace on the motherboard. Once it starts up it seems to be okay for the rest of the day, even if I power down and reboot. It's not until the next day after it has been off all night that the problem seems to re-emerge.
I think I've figured it out. Yesterday when I went to turn my machine on it did the same thing as all the rest of the week, it just stopped at q-code 19. However, I couldn't get it to start by wiggling on anything that I wiggled before. Not the power cables, not the memory, not the graphic or sound cards, not the chipset heatsinks, not even the CPU heatsink. Then I remembered I still have a dual serial port PCI card in the system (note that I have the machine in a nook beside my desk and I can only blindly reach into the case and I'm too lazy to pull the whole thing out ;-) ). So I reached behind the graphics card and pressed down a bit on the PCI card. Voila! The machine booted. This morning it booted fine as well. All my previous wiggling must have flexed the board just enough to fix the seating of the PCI card temporarily.
I now recall I had a similar issue over a decade ago when I installed a new PCI card into a machine with a case that wasn't all that square with the expansion slots. It wouldn't boot or beep at all with the card in. I remember I had to loosen the holding screw a bit to let the card sit in the slot better and then it worked.
Next week I will continue to boot my machine every morning and see if the fix lasts. If I don't report back here then that was the problem.

Okay, so my machine has booted flawlessly for 1 week. That must have been the reason I was getting the q-code 19 and was unable to boot the machine. My PCI card must have come a bit loose in the slot, maybe causing a short across adjacent pins or something. This in turn caused initialization of the PCH to fail. Pushing on the card and reseating it properly solved the problem.
Anyway, that's my story and I'm sticking to it ;-)
