Identifying Beep Codes

Beep codes produced by a computer is very important for a Computer Technician. YOu can save a lot of time troubleshooting by just listening to these beep codes. That's why it is very important to bring your own PC speaker when you are in the field. I always encounter PC's that doesn't have a PC speaker, or if there is one, it is connected the wrong way (+ to - and vice versa) so make sure to check it first before doing anything else.

Small but terrible. This is what i bring whenever i'm on the road.



THe most common beeps that you will encounter 95% of the time in repairing PC's are:

1 beep - computer ok
continous beeps / long beeps - memory error
continous short beeps - bios boot block/corrupted bios
1 long beep followed by 3 short beeps - video card error

They are the most common/standard beep codes that you will encounter daily as a Computer Tech. However if you happen to came across other beep codes that are not listed above, you can check out this list
