this is a list of beep codes that cover most all PC and by it I would check memory
#
of beeps
What’s Wrong none You’re supposed to
hear at least one beep. If you truly don’t hear anything, either
your computer’s power supply, motherboard, or PC speaker is no good. 1
short System RAM Refresh failure. Your programmable
interrupt timer on your motherboard has failed. It could also be
your interrupt controller, but either way, your motherboard will
need to be replaced to fix it. 2 short Your computer has
memory problems. First, check video. If video is working, you’ll see
an error message. If not, you have a parity error in your first 64K
of memory. Check your SIMMs. Reseat them and reboot. If this doesn’t
do it, the memory chips may be bad. You can try switching the first
and second bank memory chips. First banks are the memory
banks in which your CPU finds its first 64K of base memory. You’ll
need to consult your manual to see which bank is first. If all of
your memory tests good, you probably need to buy another
motherboard. 3
short Same as 2 beeps;
follow diagnosis above. 4 short Your problem could
be a bad timer. The system timer failed to work properly. It will
require motherboard replacement. 5
short CPU Failure. Replace the CPU or possibly the
motherboard. 6 short The chip on your
motherboard that controls your keyboard isn’t working. First, try
another keyboard. If that doesn’t help, reseat the chip that
controls the keyboard, if it isn’t soldered in. If it still beeps,
replace the chip if possible. The chip is erroring in the gate A20
switch that allows the system to run in virtual mode. Replace the
motherboard if the chip is soldered in. 7
short Your CPU has
generated an exception error. This could be a fault of the CPU or a
combination of problems with the motherboard. Try replacing the
motherboard. 8 short Your video card
isn’t working. Make sure it is seated well in the bus. If it still
beeps, either the whole card is bad or the memory on it is. Your
best bet is to install another video card. 9
short ROM checksum error. This means that the checksum
error checking value does not match the content of the BIOS ROM.
This means the BIOS ROM is probably bad, and needs to be replaced. 10 short Your problem lies
deep inside the CMOS. All chips associated with the CMOS will likely
have to be replaced. Your best bet is to get a new motherboard.
11 short Your L2 cache
memory is bad and your computer disabled it for you. You could
reactivate it by pressing -Ctrl- -Alt- -Shift- -+- , but you
probably shouldn’t. Instead, replace your L2 cache memory.
Obviously, this could lead to outright motherboard replacement. 1 long, 3 short Memory test failure. An error has been detected
in the memory over the first 64K. Try replacing the memory, and if
that doesn’t do it, the motherboard. 1 long, 8 short Display test failure. Your video card is either
missing or defective. Replace it. If its part of your motherboard,
you’ll need to replace it or bypass it.
