Disclaimer: I'm not a Mac guy, so I might need my hand held and to be walked through any suggestions.

I am helping my sister sell her old G4 FW800 MDD with dual 1.42s. Last night she came over, got her files, then wiped and reinstalled 10.4 fresh onto it. Everything was fine.

I should have left well enough alone but that CPU fan noise was bugging me. I opened it up, unscrewed the heatsink, cleaned off the old gunk (didn't touch the CPUs) and applied some Arctic Silver 5.

Ever since then, it wouldn't boot. At first it would sound the startup chime, but no image would appear on screen. Eventually the system would turn off.

I then tried Cmd+Opt+P+R, but no luck. I also tried Ctrl+Alt+Shift, no effect.

After this it started booting up, no startup sound, fans kick into overdrive until I shut it off. This morning I located the PMU button, hit it and tried booting again, same thing.

Help!
