Troubleshooting System Problems
If the computer beeps...
then...
1, 2, or 3 times...
reseat the memory SIMMs or
DIMMs. 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 there is one.
8 times...
there is a memory error on the video
adapter. Replace the video adapter, or
the RAM on the video adapter.
9 times...
the BIOS ROM chip is bad. The
system probably needs a new BIOS
ROM chip.
11 times...
reseat the cache memory on the
motherboard. If it still beeps, replace
the cache memory.
4, 5, 7, or 10 times...
the motherboard must be replaced.
