BIOS flashed now mobo is making siren noise


Dealing here with an ASUS mobo whose bios needed to be flashed ( AMI BIOS)

I found the exact model of mobo from the mobo itself on the ASUS website - I downloaded
the exact update for the BIOS - I then went to the AMI BIOS webpage and downloaed a flash utility.

I inserted the floppy - all was going well or so I thought! Update sucessful it it said and it
prompted it me to reboot.

I rebooted - and now I get a persistent siren noise from the mobo like a police car siren.

Help!   What coudl the problem be ?

Are you able to boot PC and enter BIOS?  If so, check Hardware Health section for temperature or fan speed alarm settings.  One or both may be set too low or a fan may not be connected.

       Hi jetsonx
             *You meen CMOS Beep codes. Every beep code is a signal of a particular hardware error.
             *Following link explains what every beep code mean and what you should do.
             http://www.amptron.com/html/bios.beepcodes.html
             *If you say that it is like a siren noise, this should be the thermal protection beep code. If you are able to see POST screen, enter BIOS settings and check pc health tab and disable thermal protection untill you check your fans or etc are OK. If you cant see POST screen, make sure all fans are running, heatsink touches CPU. Same for your AGP or PCI express vga cards.
The siren is usually heat, an incorrectly seated CPU or out of spec voltages, so check the fans and reseat the CPU using a thin film of good thermal paste (Arctic Silver or similar). If it still goes off, replace the PSU. As mentioned above, to see if it is a fan warning, disable all alarms in the PC health section of the BIOS. You can actually cause this by replacing a three wire fan with a two wire version. If the sensor wire isn't there the BIOS thinks the fan has failed.

since it occurred after a flash, it can be a bad flash; i would contact ASUS for it, maybe they'll send a new chip

I do not think this has anything to do with overheating, voltage or CPU issue...

it happened directly after the BIOS was flashed...

Nobus > thanks for suggestion but contacting ASUS getting them to send out a newer chip would
probably take yonks of time...any other ideas?
yes - depending on the model, there "might " be an crash free bios system - check the mobo manual
>>  but contacting ASUS getting them to send out a newer chip would

"I do not think this has anything to do with overheating, voltage or CPU issue..." that might be the cause, though. Bios was flashed and settings in bios might be in default setting what could cause the isse. Like Willcomp and Burrcm said above, do you able to access bios and check the setting? In case of bad falsing, I think you better call Asus as Nobus's comment, it might be last resort that helps to save this motherboard ...
