Motherboard BIOS Beep codes

By jasoncoetzee ·
When I turn on my machine, nothing happens, no video and the PC speaker beeps short and continuously. I read on a forum that bios manufacturers have their own custom beep codes and that shot continuous beeps mean a power supply failure. I've gone and bought a new power supply and this didn't help. I also read somewhere else that it could be a CMOS battery, video card or memory problem. I have replaced the battery, removed the video card and removed the memory one chip/card at a time to eliminate the cause but the pc speaker still beeps. Any idea what this could be?

Motherboard Manufacture

Your best source for a beep code list is the motherboard manufacture. They can implement codes beyond the default codes from the BIOS supplier.

You can also check out this Tech Republic download:


It lists a number of common beep codes.

It would help if you had mentioned your BIOS type...
