of Beeps |
Diagnosis |
0 |
If you didn't hear any beeps, then check the cords and connections to the
computer's power supply, motherboard, memory (SIMMs) and PC speaker. Make
sure the processor is properly seated and you don't have any bent pins (Socket
7 processors). |
1 |
One beep means that the computer passed the POST test (Power On Self Test).
Passing the POST test means that your motherboard, memory, video card, processor,
floppy drive are connected properly. |
2 |
The
computer has memory problems. If the video card is working, you'll see an
error message on the monitor. If not, you have a parity error in your first
64K of memory. Reseat the memory (Simms) and reboot. If this doesn't fix
it, the memory chips may be bad. Some older motherboards may require the
memory to be in the first and second banks versus the third and forth banks.
You'll need to consult your manual to see which bank is first. If you still
get two beeps, then have the memory tested by your local dealer. If the
memory is good, then the motherboard might be defective. |
3 |
Check to make sure your video card is proper seated. Sometimes you need
to pull the video card completely out of the slot and then put it back in
the slot. |
4
|
Same as 2 beeps. Your problem could also be a bad timer. |
5 |
Try
reseating the memory and rebooting. If that doesn't help, you should verify
that the memory is compatible with the motherboard. Consult your local dealer
if you are still getting 5 beeps at boot-up. |
6 |
The
chip on your motherboard that controls your keyboard isn't working. First,
try
another keyboard. If that doesn't help, see if the chip that controls the
keyboard on the motherboard is seated properly. If the chip is soldered
on the board, then the motherboard might need to be replaced. |
7 |
The
processor could be defective. Try reseating it and reboot. If you still
get 7 beeps, then your motherboard processor slot/socket might be defective. |
8 |
The
video card isn't working properly. Make sure the video card is seated properly.
If reseating the video card didn't help, then try using a different video
card. The video card could be defective. |
9 |
The
BIOS is defective. Have your dealer replace it or the entire motherboard. |
10 |
CMOS is probably defective. Replace the motherboard. |
11 |
The
cache memory is defective and your computer disabled it for you. You could
reactivate it by pressing Ctrl Alt Shift +. However, you probably should
not do it. Instead, replace the motherboard. |
