My KA655 CPU is freezing during the power up sequence, after test number 04:
KA655-B V5.3, VMB 2.7
Performing normal system tests.

Any suggestions as to what might be wrong?

You never get the dead sergeant prompt?
Looking at the manual, I think you want pages 4-20 and 4-21. If I?m right, it?s failing
on the board reset.

Is test 04 (or 03) the memory test?? Depending on the amount
of memory in the system, the memory test can take a LONG
time, MUCH longer than the previous tests.
