[QUOTE="Rob Charles, post: 15409"] I have a very similar problem on my 2Ghz G5- it works fine in all regards except when it comes to booting-up and waking from extended sleep. What happens is the fans spin (not at a psycho speed) and I get the chime but there is no action on the monitor, I reset and hard boot- the lot, but it only gets up when it wants to. A short sleep is generally OK, but after a nights sleep, thats when things set ugly. I have'nt had the patience to purpoisely leave the 'puter for 10 mins and try again, rather I persist with restarts and apple-option-p-r resets that resets the preferences (NB you hold down those 4 keys through start up and 1st chime untill it makes a 2nd chime ((or 3rd!)). This seems to get its juices going half the time. Anyway I took my mac to the reseller's & just got it back 1hr ago (2nd visit) and they ran full firmware and hardware tests and spoke to Apple Australia directly, initially they (resellers) thought it would turn out to be faulty RAM or the vid card or the internal battery supply; but the weird thing is that it does'nt seem to fail on them in the shop (*******) - they tried a transplant of vid card from display G5's and no change in performance. In short, they can't seem to narrow the problem down and Apple was satisfied that they had done all they could in this instance and asked if I would take the computer back and keep a log of faults so that the problem could be diagnosed in relation with other software active in my system- thing is that this prob 1st occured 2 weeks after I bought my 'puter and ther was no internet connection then and very little actual software on the system (I'm a pc convert) and, since I thought it was an OSX issue to begin with, the old OS went through about 5 clean re-installs and one upgrade and another 2 clean installs of Panther.
