Hey all,

If you've seen my past posts regarding my Crimson you'll know that I had to rebuild my PSU in order to solve some big power issues (random restarts, turning off, etc.).

Unfortunately some issues have cropped up again and I'm seeking advice from the community about where I might find my gremlin this time.

The current issue is manifesting as occasional un-commanded restarts in addition to the machine just simply turning off. Not in a nice way, either. Just straight to off. The PSU fan continues to run and the power switch is still set to ON.

Based on when these issues crop up--anywhere from 60 to 90 minutes after power on--I'm inclined to believe that my gremlin may reside in either the temperature sensor or the circuitry on the PS3. I know the single tower series were sensitive to environmental conditions and I'm wondering if there might be a failing component with the monitoring system.

To add to the mystery, every electrolytic cap inside the machine has been replaced. In the PSU, on the PS3, on the backplane, and each VME.

Does anyone with single tower experience have any thoughts what this issue might be?
