Power Light is always on and will not boot

Hello,

the Power Light of my Mac Pro is always on. I can switch on/off the Mac (when I push the Power Button, the 4 LEDs on the RAM Board light up briefly and then only 1 stays lit on-and the Fan also goes on) The same the opposite, when I push the Power Button for a short while, the one LED on the Memory Board goes off and also the Fan. But the power light always stays on no matter what I do. The only way to switch it off is to remove the Power. I have tried resetting the NVRAM, PRAM and SMC- sometimes I am successful ans able to start up, but then the next day no more.

Any suggestions would be greatly appreciated!

Thank you

Dorian

I'm doubtful it's a power supply issue. I've tried 3 different working PSUs and they didn't resolve the problem.

Forgive me. I forgot to mention. I am running a 3,1 with dosdude 1's Mojave. The machine has now resorted to shutting down within 2 minutes after boot rendering it unusable.

Previous shutdown cause is -2. What does that mean?

@dwcdv - Did you try looking at the motherboard while its on with the sidepanel off,

look around for some lights near a button,

Press said button and post a picture of the lights
