Computer Beep Codes

[RACKnRAIL]

I just added a used motherboard to a tower I had. I put it all together and it fired up. It reads all 3 sticks of ram, which totals 1 gig without a problem. I was able to install windows, but the boot process beeps and hangs. I get 2 short beeps, a pause, and then another short beep (3 total beeps). It then hangs, saying press the F1 key to continue, and then boots into windows without any problem. I have tried resetting the bios to default, but no cigar. Any ideas what the beeps are about? I have tried removing ram sticks and even with one 512mb stick it still beeps. I honestly don't think it's the ram, which was my first thought. BTW, I did add a heat sink to my chip. It was socket A, but that wouldn't cause beeps, would it?

Check the model number and look for the user manual online. That would be the first step I take anyway. That is unless there is a jumper to turn it on voiced error codes, this is an option some Asus motherboards have.

I've looked at the beep codes, as posted, but nothing explains 2 shorts, a pause, and another short beep. I tried googling it and get no solid answer.

I do have the pdf manual. I will take another closer look at it for clues.

Thx!

Also be sure that you have the correct number of drives selected. For example, if you only have one hard drive, be sure your BIOS is set for only one drive (set additional drives to NONE rather than Auto-Detect, etc.).

Be sure you check that setting not only for your hard drives, but for your CD/DVD drives and the floppy drive, too.

If you have none, make sure the setting in the BIOS says NONE.

Did that already. thx!

[Mels_Smileys45]

DO you have the motherboard properly mounted? I left out one of the rubber gaskets one time and it did the beeps. But it also did random restarts.

[RACKnRAIL]

Yes, I did take care in installing everything from mounts to jumpers to my heat sink. I will try a few different ideas when I get home today.

I'll keep ya'll posted.

RACKnRAIL, this doesn't fit into the codes but just as a precaution how long has that mobo been sitting out? I'm thinking your CMOS battery may be dead. If you have any analog/digital multimeter to measure the voltage across the cell?

That's something I haven't thought of yet. Thanks, I will give it a try.

Edit: Update: That was it!! You're 1cooldude and a genius. :You_Rock_Emoticon:

Thanks to all for your input. Case closed....I hope!!

I now have another clunker computer. It has 1800+ (1.5 ghz) AMD processor with 1 GB of ram, 64 MB graphics, 2 80 GB hard drives, and a decent DVD all-in-one burner.

glad to be of service RACK. :)

Whats the chip set? Think I have a 939 3000+ (Think its a 3000+, maybe 3200+) lying around here. If you want it pay the shipping and its yours, a couple pins are slightly bent but could probably be straightened fairly easily, that is if they didn't fit the way they are now.

Damn it you beat me to it.

I have repaired sevral computers (mostly Dels) where all the problem oit had was that the damn little enternal NiCad battery was dead. Most are good fopr about 3yrs.

had a few of those die and always keep forgetting to check first.
thanks for the help.

Hey, it's a good thought, but I will stick with the 1800+. Thanks just the same!!
