I've replaced everything in this Z800 except the fans. Used, from another working Z800 PSU, memory, graphics card, CPU's and motherboard. I found it 'dead' after an electrical storm, although it was on the surge protector. Router and cable modem was not affected. I don't think anything came through the network.
All soon as I plug in the AC, all the fans start running on low. After 30 secs, the CPU fans go to high speed. This happens with both the old and new motherboards and the old and new CPU's.
I disconnected everything, including the bay and back chassis fans and still the Z800 starts itself when powered.
No video comes out of any graphic card I install, so no bios to see. Odd?
I get 3 beeps when I press the start button, one time but no red light flash, just one green power on flash.
Could this chassis be possessed?
So First, what would make a Z800 start without pushing the start button?
