Hoping that someone might be able to help, as I think I have tried pretty much everything and I’m running out of ideas now!


It’s a G5 dual 2.7GHz that refuses to get past the grey apple logo screen no matter what I do!


  • everything passes the extended apple hardware test (2.5)
  • 3GB of RAM (2x1GB brand new from crucial)
  • won’t start from a original OS 10.58 disk
  • passes disk utility when connected to another mac via FW target mode
  • nothing other than keyboard/monitor attached
  • all of this done;
  • tried alternative HDD’s without any joy
  • won’t safe boot
  • stays at the grey apple logo screen and the fans then start revving up excessively


Any other suggestions or advice very gratefully received!

PowerMac, Mac OS X (10.5.8), G5 dual 2.7GHz
