The beeps are post during
post the very first work is done by the ram,all the memory in the ram is first
transferred to the hard disk,and remains active untill turned off. make sure
that your RAM is securely seated One bad lead can cause a computer to continue on a cycle or
to shutdown or fail to detect your hard drive Test all leads that attach to your hard drive including
electrical extensions,IDE,SATA the leads from your ((motherboard
to your hard drive)) make sure they have a secure connection and are not
faulty or just replace them they could be faulty a computer needs its connections to continue its cycle and
to have and end to function
obvisously the
beeps are windows searching for some hardware it could be RAM cd/dvd hard drive
or motherboard all of these must have secure connections for the computer to
work
make
sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have
secure make sure the connections and are not faulty even the electrical
extensions or just replace them they could be faulty a computer needs its
connections to continue its cycle and have an end so any faulty leads will end
up with a computer error
hope
this helps
Well...Dell doesn't document a 3-2-1 beep code, but the beep codes that do start with 3 all point to the motherboard as the problem. Hope this helps.
