It was working a several years ago when I last turned it on and I decided to power it on recently to see if it would boot - it didn't.  Hard drive won't spin up to speed (out of system on another PSU, bearings likely sticky).  More importantly no boot chime, power light comes on green in half a second, then no amber or anything else, just stays green.  Pulled the covers off the PSU connectors for the boards so I could measure in-situ.  Power rails all seem ok (5.xx,12.xx,-5.xx,-12.xx,3.30,3.56?? on yellow lines, and 14.3??? on 2 white-ish lines nearest the rear)  I was hoping it was the power supply but no.  Doesn't seem to match symptoms elsewhere for dead battery/etc (But maybe it is??)  Anyone else seen this or had this happen?  I've reseated the Extreme Graphics card, CPU, ram, and PROM.  I also removed the CDROM (in case it was causing issues).  Not an SGI expert here, just wanted to play with it a bit.  Ideas?  Haven't tried serial diagnostics but figured it hadn't gotten that far since the light didn't go amber.
