Beep codes are your motherboard's way of telling you exactly what's wrong — if you know the language. Here's the complete beep code decoder.

AMI BIOS Beep Codes

1 short: DRAM refresh failure — reseat RAM
2 short: Memory parity error — test RAM sticks individually
3 short: Base 64K RAM failure — replace RAM
5 short: CPU error — check CPU seating and power
1 long, 2 short: GPU not detected — reseat graphics card
1 long, 3 short: GPU memory error — try a different GPU

Award BIOS Beep Codes

1 long, 2 short: Display issue — reseat GPU and check monitor cable
Continuous beep: RAM not detected — reseat or replace
Repeating short: Power supply issue — check PSU connections

Step-by-Step Fix

1. Count the beeps (short vs long) 2. Match to your BIOS manufacturer 3. Reseat the indicated component 4. Clear CMOS (remove battery for 30 seconds) 5. Test with minimal hardware (1 RAM stick, onboard graphics) 6. If beeps persist, the component needs replacement
