Symptom Charts
Startup
RAM failure occurs

1 Remove top RAM SO DIMM (if present) and restart computer.
If startup sequence is normal, replace RAM SO DIMM and
retest.
2 Replace bottom RAM SO DIMM and retest.

2 Reset PRAM (during startup, hold Command-Option-P-R
keys until the second startup tone is heard).
3 Remove expansion module from left expansion bay and restart
computer. If startup sequence is normal, insert expansion
module and retest.
4 Remove expansion module from right expansion bay and
restart computer. If startup sequence is normal, insert
expansion module and retest.
5 Disconnect hard drive connector and restart computer. If
startup sequence is normal, reconnect cable and retest.
6 Replace hard drive connector board.
7 Replace hard drive.
