I have a friends computer that i am trying to fix. It goes into a post beeping error when it starts up. Long continuos beeps. I have reset the CMOS and it actually works. I go through everything and it seems to be fine. Then I power it down. After about two hours I check it again and same problem. Could this be the CR2032 battery located on the motherboard?
 
yes

Give the wrong symptoms, get the wrong solutions.
 
If you have a battery tester then make sure the coin battery is at or near 3 volts, not less than about 2.8.
Also, you can tell if the clock settings in your bios wont stay after you have set the time correctly, then you know its the battery at fault.
Batteries usually last somewhere from 5 to about 7 or 8 yrs, but some even less than 5 yrs, especially, i have heard, if the wrong one is used. Most take the standard 2032, but some take other numbers. As long as the battery fits it will work but it wont work as long as it should if its the wrong battery number. There is a 2016 and a few other battery numbers.

Thanks for the advice! Very much appreciated.
Going out to get a battery now.
 
Hint: They are $1 at the $1 store and they are $5 at computer store!

Okay.. need some more advice.. wasn't the CMOS battery. It is still doing it. I shut it down and rebooted an hour later and getting long POST beeps. I can clear the CMOS again and it will probably work.. there has got to be something else. any ideas?

Good advice + great people = tek-tips
 
You didnt state which bios you are running, so i put all three there.


Good advice + great people = tek-tips
 
The beeping continues and is long.. no limit on the amount of beeps it is limitless.. is also a phoenix bios. I have tried everything and am thinking it may be a motherboard problem.
 
the thing that is buggin me is it works fine everytime i reset the cmos. just when it is powered down and restarted 20 minutes later it goes into the POST beeps.

There-in lies the answer, but we have to find it.
I wonder if your power\on button is faulty?
Can you dissconnect the 2 pins from the power\on from the mobo. Then all you have to do is use a flathead screwdriver to boot up or turn the computer on. Screwdriver does exactly the same, just the flat head against the two pins where you took the wires off at the mobo, touch those 2 pins with screwdriver and turn the computer on, see if all is well. If so, then its your power\on switch that is the problem. If not, we gotta look elsewhere.


If the above doesnt work, then i suggest you take out all your pci cards except any video card and then boot up and see if all is well.




Good advice + great people = tek-tips
 
I'll try the screwdriver thing.. the only pci card installed is the video card.

I've tried the RAM too, thinking that may have been the problem. Running out of options.. i'm almost positive it is the motherboard.

 
Dont take offence, but are your bios jumpers set on one and two, as opposed to 2 and 3? I pretty much know all the answers but we have to always start from the basics and work our way to the tougher situations.


Good advice + great people = tek-tips
 
How are you re-setting the bios? Do you mean you are moving the jumper from 1 and 2 to 2 and 3 and then back again?
Or are you setting the ide and other parameters in the bios manually each time?


Good advice + great people = tek-tips
 
Yes I am moving the jumper from 1 and 2 and then 2 and 3 and back again.

After that i go in and change the internal clock to the correct time. Do I need to change anything else???

Thanks for all your help.
 
.. and just a further message.. if i don't move the jumpers there is no way for me to get into the bios.. it is a necessity to move the jumpers when the POST beeps are going, the only way i can get rid of those beeps is to move the jumpers resetting the CMOS.
 
Okay, heres what to do.
Go into the bios and find the setting similar to "default" setting, or standard settings, whatever the saying is, its the basic default settings.
Some setting in the bios MUST be causing all your problems, like maybe the wrong ram setting, something like that. Maybe the timing of the ram, or the x factor for the cpu.
We had better get the info from you on what kind of mobo and what cpu.
However, do the "default setting" in your bios first.
thanks

Hi qmann,
Just a thought. Did the system boot up when it beeps?
If it does, then it could be the alarm of the temp for the CPU or system board. Check if the BIOS has an item like PC health etc. Check if the over temp alarm is on and the trigger temp is not set to too low.

 
I'm suspecting a bios setting too as you can see.


Good advice + great people = tek-tips
 
The system does not boot up at all on POST, just goes directly to beeping.. cannot get into the BIOS unless i reset the CMOS

As for the motherboard it is an Asus AX45-V. The CPU i'm not sure.. coming up as 1.6 ghz but that is at the default bios settings. I will try to see if there is an alarm for temp of the system board as well.. thanks all!
