Each motherboard has its own boot up tones in terms of number, total time, sequence, etc. If there is an error before the boot up sequence, then you should count the number of tones it gives you. Normally, if there is an error, the computer won't play the POST OK boot tone which is one short beep. For all the errors that appear before that, check the cables, AC power, and loose connections. If it keeps repeating, visit a certified computer repair store to properly diagnose it.
