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 Beep	Keterangan
1 buyi pendek	Eror Ram / Cek Ram
2 buyi pendek	Cek masing - masing konektor sirkuit
3 buyi pendek	Ram Failure
4 buyi pendek	Gagal Seting Waktu
5 buyi pendek	Proses Gagal
6 buyi pendek	Eror Keyboard
7 buyi pendek	Virtual mode exception error
8 buyi pendek	Gagal membaca Memory
9 buyi pendek	ROM BIOS checksum failure
10 buyi pendek	CMOS shutdown Read/Write error
11 buyi pendek	Cache Memory error
1 panjang, 3 pendek	Conventional/Extended memory failure
1 panjang, 8 pendek	Display/Retrace test failed

1 panjang, 2 pendek

Mengindikasikan VGA card yang tidak terpasang secara benar, atau dikarenakan GA EROR
