There are three main sets of reasons that the tune/music is playing
- Processor, Heatsink/Fan and Power Supply related tune/music.
Processor Related Tune/Music
1. The processor is missing. Insert a processor and set the jump-
ers.
2. The processor is not seated correctly. Check and make sure
the ZIF socket lever is down.
3. The processor has bent or broken pin. Fix or replace the
processor.
4. The processor is malfunctioning/bad. Replace the processor.
Heatsink/Fan Related Tune/Music
1. The processor does not have a heatsink or fan. Add a heatsink
with fan - all modern processors need it.
2. The processor has a passive heatsink only. Add a fan.
3. The processor’s fan/heatsink simply isn't cooling sufficiently. Use
a larger or more efficient heatsink/fan.
4. The processor is overheating because the fan stopped. Replace
the fan.
Power Supply Related Tune/Music
1. The power supply’s voltages did not meet the ±10% specifica-
tion. Use a voltmeter to check the +5V and +12V lines, or
change the power supply to a different model/brand/type.
2. The power supply’s wattage is too low and cannot meet the
system's continuous power requirements. Use a power/watt-
meter to check the system’s power consumption, or change to
a power supply with a relatively larger wattage, e.g. 250W or
300W.
3. The power supply cannot meet the transient/instantaneous
demand, e.g. happens when HDD motor, etc. turns on. Use an
oscilloscope/DSO to monitor the 5V and 12V lines for/during
those transient stages. If so, change the power supply to a
different model/brand/type.
