Mobo alarm sounds constantly at startup

MY ax34 mobo recently started sounding an alarm constantly at startup. The video displayed "BIOS ROM checksum error Decting floppy drive A media Drive A error. System halt. I have changed CPU, memory, power supply, disconnected everything except mb, cpu, mem, and video, and still the same.

I can't access the "A" drive to boot so I don't know how I am going to flash the bios.
Is there another way?
DONLEL ESTAB Sep 18, 2007

I took the CMOS battery out for 4hrs, shorted the CMOS jumper, returned it to normal, but when I turn it back on, I get the same message:

"BIOS ROM checksum error

Decting floppy drive A media
Drive A error. System halt."

It will not access drive "A" thus I cannot boot
from the floppy. All the while the alarm sounds continously.

Firist thing i would do is clear the CMOS by means of the jumper onboard, and at the same time take the button cell battery out of the board and let it sit for 5ish mins to clear the cmos completely. If when you reinsert the battery and put the jumper back you still have this issue i would recommend flashing the BIOS. If you have never done this make sure you dont have any storms near and if you have bad power issues (electric company sucks) i would recommend using a backups so you dont damage the BIOS. Dwonload http://usa.aopen.com/userdownload_List.aspx?RecNo=4490&Model=AX34 Follow the instructions to flash your bios. HOWEVER READ THIS!!!!!! Do you have a: ax34 ax34 II ax34 Pro ax34 Pro II ax34-U If you have ANYTHING other than the ax34 then goto http://usa.aopen.com/download.aspx to get the one for the right version. IT IS ESSENTIAL THAT YOU DO OR YOUR MOTHERBOARD WILL BE UNUSABLE!!! Anywho let us know :-D

Typically if you remove the cmos jumper and insert the floppy with the bios image on it it should reimage it automatically. Just make sure the image in on the floppy's root directory and not in a folder.

Ultra m923 mid-tower case won't stop beeping

The problem is the board on the case's display. It has temp alarms for your components(video card, hdd, cpu), there are temp probes for you to set so you can monitor these temps. However the board that controls these functions, or at least mine and many others I have read about, is defective. It will change display constantly and sometimes have garbage display. It is setting its own limits for what is considered a hi temperature. The limit it has set for one of your components is < room temperature so it thinks you are having an overheating problem. You can manually set the limit for overheat and it will fix it for a while, but it will prob happen again.

No sound output

You'll want to verify that the onboard audio is enabled within the bios first, beyond that the audio codecs for that mobo should be the Realtek AC97 drivers, go to this link to obtain them. You have a choice of two - the AC97 standard codecs or the HD codecs (I would probably try the HD codecs first). I would also be curious as to whether the audio hardware is showing up in the device manager at all (especially if it has the yellow exclamation point next to it).

Based on what you posted about a bios update being the catalyst I would definitely check the onboard audio enabled within the bios option first...

Please post a little more info (especially about what the device manager says) or your results from the reinstall of the AC97 drivers...

Aopen ax34 tamper alarm--how to reset????

I don't think that board actually has a tamper alarm in the bios, password security yes but I saw no mention of a tamper alarm. Besides, a tamper alarm won't stop the pc from booting, it just lets you know that the case has been opened....sorry. I think you likely have a mainboard/ram issue.

First thing is to clear the bios. Here's how. Right beside the floppy connector, there is a jumper labeled 'JP14'. Please do the following

Turn off the pc and remove the ac power cord.
Remove the atx power connector from the mainboard (from power supply).
Locate jp14 and move the jumper from pins 1 and 2 to pins 2 and 3. Wait 10 seconds.
Put jp14 back to pins 1 and 2
Reconnect the atx power connector.

Or you can just unplug it from the waal and remove the bios battery for an hour.
sa code
Try to fire it up again. If it still won't boot, then let me know the number of beeps it makes and the pattern to the beeps ie: one long beep then another long beep or 1 long beep then 2 short ones. These beep are actually telling you what the problem is.

Hope this helps! Post a comment and let me know how you make out.

Mer cury PVM7 mobo wont display on monitor

So I think you are saying it did work and then stopped, right?

If that's the case then I would try booting into the BIOS setup and reseting it first. If that does not work then I would reboot into the BIOS again and see if there is something there you need to enable for the AGP port to function.

If all this fails then you most likely have a bad motherboard. It's probably not worth the money to consider having it repaired, and I doubt you'd find anyone who's even interested trying.

Good luck.
