More about Bios Beeps
While the system boots up, the BIOS
checks the main hardware components like the motherboard,
the system's memory and the video card to initiate the
booting process. This process is known as power on self
test. Now, throughout this process if anything or any
hardware doesn’t respond as per the requirement then
system would start bios beeps in order
to indicate the user to check the system functionality
again. Sometimes due to system fan or a memory stick,
system beeps. However, there is a standard way of bios
beeps. So, we should try to understand this
and troubleshoot accordingly.
So, the moment we heard the bios beeps,
we need to pay attention to it and of course the length
of the beeps which could be short and long. It is better
if write down your observations. For example, one beep
means RAM failure. The Problem is the Mother board or
failed RAM. We need to troubleshoot motherboard and/or
the RAM. If the system gives two beeps than it is Parity
circuit failure. Again it’s a Problem with Mother Board
or failed RAM. Solution could be Troubleshooting the
motherboard and/or the RAM. If its three bios
beeps than Base 64K RAM failure. Problem could
be failure with in the first 64k memory. We need to
troubleshoot the motherboard and/or the RAM.
Four bios beeps mean system timer failure.
Issue is one or more of the system timers on the motherboard
has failed; usually indicates motherboard failure. Solution
is to troubleshoot the motherboard and we may need to
replace it. If it gives five bios beeps
then it indicates processor failure. The Problem is
the processor which is generating an error condition.
So, we need to check all these with the BIOS manufacturers
like AMI, Award and Phoenix and work accordingly.
