My Bleeping Z800 server chassis

AFSIK, this z800 chassis is possessed. I might have missed something during my troubleshooting process but what? Our company uses Z800's for editing video and I have fixed many of them.

The problem with this chassis is: The fans start running as soon as I plug in the power cord. I changed the motherboard, the PSU and the 2N3903 ambient sensor in the wiring harness. The fans still run, forever...

This Z800 stopped working, during the evening of a electrical storm. It was on a surge protector and nothing else in our network had any problems.

A surge may have come in through our HDMI network, through the monitor common ground, but no other devices were affected.

I have more time spent working on this unit then it's worth but now it's my personal pride keeping me going.

I would have thought, pressing the CMOS reset, on both motherboards I have tried, would have canceled all knowledge the unit has, about the last failed startup. Everything is disconnected from the motherboard except the fans. I even disconnected the Start button connector! It still starts the fans.

I've tried a 10 second reset on the PSW. Did not help. I get 3 beeps after I pull the AC plug but I've changed the CPU in this replacement motherboard. What else could it be? H.E.L.P. please
