[CUBE] PowerLogix 1.2, bad news

[Doug Wambold]

I had a similar experience with the Powerlogix 233 1.2 GHz card.  
Initially, the upgrade worked very well, delivering truly impressive 
performance.  Shutdowns and reboots caused no problems until this 
morning.  Pressing the power button lit the various LEDs and started 
the fan  However the light in the power button immediately went out, 
and the Cube failed to boot.  LEDs and fan remained on, LCD panel 
remained black, and no start up chime was annunciated.  None of the 
usual reboot, PRAM zap, motherboard reset switch fixes corrected the 
problem.  Complete disassembly and reassembly yielded the same result.  
However, upon reinstallation of the original 450 MHz processor, the 
cube worked flawlessly again.

It is a mystery.
