Beep Sounds While Booting a PC 17 years 3 weeks ago #2179

HI friends

Beep codes are the little beeps you hear out of the PC speaker whenever you turn the computer on. They are your computer's way of letting you know what's going on when the video signal is not working. These codes are built in to the BIOS of the PC
There is no official standard for these codes due to the many brands of BIOS that are out there, but the two main brands are Phoenix and American Megatrends

in the case of AMI BIOS Beep Codes

none You're supposed to hear at least one beep. If you truly don't hear anything, either your computer's power supply, motherboard, or PC speaker is no good.

1 One beep is good! Everything is A-OK, that is, if you see things on the screen. If you don't see anything, check your monitor and video card first. Is everything connected? If they seem fine, your motherboard has some bad chips on it. First reset the SIMMs and reboot. If it does the same thing, one of the memory chips on the motherboard is bad, and you most likely need to get another motherboard since these chips are soldered on.

2 Your computer has memory problems. First, check video. If video is working, you'll see an error message. If not, you have a parity error in your first 64K of memory. Check your SIMMs. Reseat them and reboot. If this doesn't do it, the memory chips may be bad. You can try switching the first and second banks memory chips. First banks are the memory banks in which your CPU finds its first 64K of base memory. You'll need to consult your manual to see which bank is first. If all of your memory tests good, you probably need to buy another motherboard.

3 Same as 2 beeps; follow diagnosis above.

4 Same as 2 beeps; follow diagnosis above. Your problem could also be a bad timer.

5 Your motherboard is complaining. Try reseating the memory and rebooting. If that doesn't help, you should consider another motherboard. You could probably get away with just replacing the CPU, but that's not too cost-effective.

6 The chip on your motherboard that controls your keyboard isn't working. First, try another keyboard. If that doesn't help, reseat the chip that controls the keyboard, if it isn't soldered in. If it still beeps, replace the chip if possible. Replace the motherboard if the chip is soldered in.

7 Your CPU could be broken and no good. Either replace the CPU or buy another motherboard.

8 Your video card isn't working. Make sure it is seated well in the bus. If it still beeps, either the whole card is bad or the memory on it is. Your best bet is to install another video card.

9 Your BIOS is bad; replace it.

10 Your problem lies deep inside the CMOS. All chips associated with the CMOS will likely have to be replaced. Your best bet is to get a new motherboard.

11 Your cache memory is bad and your computer disabled it for you. You could reactivate it by pressing -Ctrl- -Alt- -Shift- -+- , but you probably shouldn't. Instead, replace your cache memory.

Then friends In the case of Pheonix types

1-1-3 Your computer can't read the configuration information stored in the CMOS. Replace the motherboard.

1-1-4 Your BIOS needs to be replaced.

1-2-1 You have a bad timer chip on the motherboard; you need a new motherboard.

1-2-2 The motherboard is bad.

1-2-3 The motherboard is bad.

1-3-1 The motherboard is bad.

1-3-3 Same as AMI BIOS 2 beeps. Replace the motherboard.

1-3-4 The motherboard is bad.

1-4-1 The motherboard is bad.

1-4-2 Some of your memory is bad.
