Digital Code dan Beep Code Pada Motherboard

Sebagai teknisi komputer tentu kita sudah mengenal apa itu BEEP Code. Beep Code merupakan indikator pada sebuah motherboard yang bunyi pada saat sebelum terjadinya Booting Windows.  Ada bermacam macam bunyi BEEP, Bunyi  Beep terjadi jika motherboard mengalami eror/permasalahan sehingga pada saat melakukan star, Windows tidak bisa Booting.

Bunyi Beep mgnindikasikan eror yang terjadi pada PC System Hardware yang mana Firmware tidak bisa mengeksekusi dikarenakan ada permasalahan yang terjadi pada salah satu perangkat yang ada pada komputer. Berikut merupakan detail singkat Kode Beep dan Kode Digital untuk mengetahui Eror pada PC

Kode BeepKeterangan
1 buyi pendekEror Ram / Cek Ram
2 buyi pendekCek masing - masing konektor sirkuit
3 buyi pendekRam Failure 
4 buyi pendekGagal Seting Waktu
5 buyi pendekProses Gagal
6 buyi pendekEror Keyboard
7 buyi pendekVirtual mode exception error
8 buyi pendekGagal membaca Memory
9 buyi pendekROM BIOS checksum failure
10 buyi pendekCMOS shutdown Read/Write error
11 buyi pendekCache Memory error
1 panjang, 3 pendekConventional/Extended memory failure
1 panjang, 8 pendekDisplay/Retrace test failed
1 panjang, 2 pendekMengindikasikan VGA card yang tidak terpasang secara benar, atau dikarenakan GA EROR
