Phoenix BIOS Beep Codes

1-1-3 Your computer can't read the configuration info 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 You'll need to replace the motherboard.

1-3-3 You'll need to 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.

2-_-_ Any combo of beeps after two means that some of your memory is bad, and unless you want to get real technical, you should probably have the guys in the lab coats test the memory for you. Take it to the shop.

3-1-_ One of the chips on your motherboard is broken. You'll likely need to get another board.

3-2-4 One of the chips on your motherboard that checks the keyboard is broken. You'll likely need to get another board.

3-3-4 Your computer can't find the video card. Is it there? If so, try swapping it with another one and see if it works.

3-4-_ Your video card isn't working. You'll need to replace it.

4-2-1 There's a bad chip on the motherboard. You need to buy another board.

4-2-2 First check the keyboard for problems. If nothing, you have a bad motherboard.

4-2-3 Same as 4-2-2.

4-2-4 One of the cards is bad. Try yanking out the cards one by one to isolate the culprit. Replace the bad one. The last possibility is to buy another motherboard.

4-3-1 Replace the motherboard.

4-3-2 See 4-3-1

4-3-3 See 4-3-1

4-3-4 Time of day clock failure. Try running the setup program that comes with the computer. Check the date and time. If that doesn't work, replace the battery. If that doesn't work, replace the power supply. You may have to replace the motherboard, but that is rare.

4-4-1 Your serial ports are acting up. Reseat, or replace, the I/O card. If the I/O is on the motherboard itself, disable them with a jumper (consult your manual to know which one) and then add an I/O card.

4-4-2 See 4-4-1, but this time is your Parallel port that's acting up.

4-4-3 You math coprocessor is having problems. Run a test program to double-check it. If it is indeed bad, disable it, or replace it.

Low 1-1-2 Your motherboard is having problems

Low 1-1-3 This is an Extended CMOS RAM problem, check your motherboard battery, and motherboard.

got it from a site. I hope they don't mind. can't remember the address.

Good attempt on a very difficult subject, the only problem is that codes vary from machine to machine. I'v got a good site here which can lend a helping hand, dunno if you want to add it to your main post. GJ :)

It's true that codes vary from machine to machine. My ASUS board beeps for every USB device attached. So I usually get four beeps at startup.

However, sometimes there's an extra beep or two in there that sounds different. *shrug*
