Yo,
So while this is by no means conclusive, seems like a PSU issue..and that's easy to check. I've rebuilt like 13 Indy Nidec brand PSUs and I've seen one the PSU (on bench with load tester) FULLY START while missing it's 5V rail entirely! So I know the PSU will turn on while it's missing some voltages.

While you likely don't have a current-limiting setup to help protect things, since it's doesn't work anyway I suggest the following (I'm not responsible for anything I say here :-).

Go here: https://wiki.preterhuman.net/Indy_Power_Supplies

Unhook BOTH power and IDC connectors from the Indy main board to the PSU (PSU cables now fully disconnected), get a multimeter with probes that fit into the back-side of the LARGE WHITE PSU connector (so you can touch the crimped wires with a needle probe).

Plug in the PSU and it will automatically start. Voltages WILL BE UNSTABLE (no load) but kind of close, use wire colors in the URL to test for voltage that's close on 5v, 3.3v, and 12v (molex drive connector end). Likely your CPU needs 5v and likely that's like less than 1v or gone!

If you find this is the case then it's a good bet (not a guarantee) that a another, working, Indy PSU will solve your issues as you may be have been underfeeding your CPU this whole time.


I'm not trying to plug my rebuild service, since your in Amsterdam and I'm in the USA it's likely too costly to do business together, but if you can find another PSU near you, get it this after basic testing, and I think things will be different.
