How to solve code D4 on the PC Analyzer

Mainboard my strange disease, after check with PC Analyzer, it appears very clear code D4. According to the horoscope, which exists and is circulating in cyberspace after asking questions and looking at various forums both from Google and fro. Apparently it can also end, he checks it according to its type mainboard BIOS, such as below:

1. Those who have a mainboard with BIOS AMI If the code (D4) on your PC Analyzer, then Chipset initialization / auto memory detection about to begin. Check SIMM for mismatch.
2. If you only have a mainboard with BIOS Compaq, would appear the code (D4) Back in real mode to clear real-ready mode.
3. For those who just bought a mainboard with Phoenix BIOS do not forget to see if any code (D4), then do not just stare Pending interrupt error. (Beep) = 4 -2-2-1

Hopefully succeed, do not forget to check the incoming voltage to the RAM slots, RAM slots exist near an IC Regulator to voltage to the RAM and then check on the third leg voltage IC that there should be 5 volts. If not there, automatically we must seek instead a way to find the code from the mainboard former IC anymore. If there is nothing new, and it was hard when looking for a new one, unless ordered to the manufacturer by way of a Google search would be very powerful.
