Now, I don't even hear a clicking sound at start. I removed all the blades, still no click. I see only 1 yellow light (next to the PCI connection), but no red light (next to Ethernet).
Will it help if I replace the PSU, or is this cube dead forever ?
I think the yellow LED is a status of the clock set to High from what I remember? Someone confirm?
Do you have a different power supply to at least test with at all? I'd start there.
