So it would appear my G5, Dual 2.7 has passed on... went away from it for 30 - 45 minutes last night, came back to a wind tunnel since the fans were at full pelt. No idea what happened since the screen was in standby.
Held the power button down to shut it all off, powers back up but won't chime as the graphics fan is spinning away at full speed due to no proper POST. The strange thing is, the 4 fans for the liquid cooling system doesn't build up to full speed. It feels as if it's ticking over at 1000rpm with a slight breeze as the loudest part comes from the graphics card fan.
Tried powering it up with the hard drives disconnected, no go.
Tried powering it up with no display connected, no go.
Tried powering it up with the PRAM battery out, which is not even 8 months old. No go.
There's no leaks, no fluid attempting to run to the front of the side panel. Everything is blown dry. Even the plastic tray chamber. No odours. There was a slight crystallisation around the back of the unit (where the processors are) but nothing big. Almost like a little bit of salt, very dry looking but doesn't look like it's in contact with the logic board or processors it's that small. As you can see the gap. It's been this way for a few months, at least.
Tried minimal ram, no go. I know for a fact it's not the ram. It's been rock solid for 7 years.
There also no red LEDs or such warning indicators. Powers up as if it was normal running, just no chime.
Can't see much point trying to get it repaired as the cost will no doubt mount up... for something so obsolete, or rather, vintage. Very sad day though.
Any ideas? it definitely sounds something related to the logic board...
