I have a 20" 1.8ghz G5 with the famous not-so-hot capacitance on the motherboard. None of the capacitors has actually failed, but I was running into seemingly random freezes very regularly and had eliminated most other potential causes (memory, drive issue).
As it turns out I found the reason it occurred at seemingly random times. On the iMac by default energy saver powers down the drive as often as possible. Depending on system load this can be fairly often. The apparently random freezes were occurring when the drive powered back up - the sudden power drain from accelerating the drive was the trigger for the capacitance issue raising its head. Not that this will solve problems with failed capacitors (although it may help prevent them), but turning off that feature in energy saver (system preferences) may solve freezing problems that can't be traced to bad RAM or disk problems. cheers -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
