Hello Gurus, I have encountered an issue with my Intel i7 5820k CPU and MSI x99s Gaming 7 motherboard. Few days ago I turned on the computer, but it never got to Windows and the debug led stayed at 19 - south bridge power initialisation. I've reset BIOS to no avail, then opened the case, fully disassembled the components, cleaned everything, changed thermal paste and then encountered the same problem. I have 2 sets of 4x4GB Corsair Vengeance RAM and I was starting to suspect one of the sticks. Took out all of them and inserted only one - same problem and same problem with all the other 7 RAM sticks. I then took out all the RAM, turned on and this time got an error code for no RAM. Tested all the sticks on the first RAM slot and every stick booted to Windows. Everything was fine with dual channel as well, but when I tried triple channel RAM, I again encountered error code 19. It is clear that this is something with either the CPU or the motherboard. I prefer to avoid buying expensive 2011-3 CPU or motherboard. Any clever ideas or nifty methods to find out which one exactly is causing the problem?
