What to Do If the Computer Beeps
If the system beeps...
then...
1, 2, or 3 times...
reseat the memory SIMMs or DIPs. If the system
still beeps, replace the memory.
6 times...
reseat the keyboard controller chip. If it still beeps,
replace the keyboard controller. If it still beeps, try
a different keyboard, or replace the keyboard fuse,
if the keyboard has one.
8 times...
memory error on the video adapter. Replace the
video adapter, or the RAM on the video adapter.
9 times...
