Just to be sure...
You get a LONG (MAJOR) signal category, RED LED &
then a SHORT (MINOR) signal category, WHITE LED.
Major – the category of the error; Minor – specific error in that category
The AUDIBLE repeats 5 times, and the VISUAL until power is removed.
The Main-Board displays a power failure (crowbar).*
Indicates potential power system failure.
1 Reduce to minimum config (CPU, Main-Board, PSU,
Single memory DIMM) and isolate failed component.
2 Reduce further if issue persists.
3 Test known good PSU.
4 Replace affected component.
5 If unable to confirm source, replace CPU, Main-Board, PSU.
So you eliminated the PSU and CPU? The memory module also passed?
