Solved Replaced Both Cpus And Logic Board Error B Led Still Lit Power Mac G5

Chosen Solution

My PowerPC G5 dual quad core failed to boot, the diag leds indicated a failed cpu B. I replaced both cpus, same error. I then replaced the Logic board and STILL have the same error. WTF? Suggestions?

Maybe it’s the RAM. If you have more than one module, see if it works with just one.
