suffered from a whole slew of bad capacitors?
My iMac G5 (20", 1.5 GB RAM) has the dreaded blue screen on startup. I have searched the archives without finding anything to throw light on identifying the issue.
I have spent four days on this problem and reinstalled the system (both A&I and clean install) several times. The most significant fault finding/eliminating includes:
-run Disk Utility to repair permissions & repair disk (no disk errors)
-zapped PRAM & replaced battery
-erased & zeroed internal drive and reinstalled Mac OS X 10.4
-run Apple Hardware Test (no problems reported including memory)
-removed each memory array & rebooted
-swapped memory arrays in slots (no change)
-tried booting with & without mouse & keyboard (keyboard is faulty)
-booted with different keyboard & mouse
-reset PMU/SMU (I think)
-restarted in Safe Boot mode and ran without issues (able to update OS and other software to current latest versions using System Updater & internet)
-used as target disk for G4 host PPC (ran as expected)
Problem still persists. Whenever I boot into 'normal' mode I get the blue screen. I assume it is a hardware issue and the normal boot process hangs when it gets to a process/address/peripheral that is not active during Safe Boot.
My question - how do I determine which component has the fault or is it time to bite the bullet and take it to a tech? (I did take it to the Apple Genius Bar and he guessed the HD was probably failing but it runs for hours when booted into Safe Boot mode).
