Well, after a bit of nosing around on the internet and in a few other forums, I can across the keen idea of going into Single User Mode and removing video-related kext files from the systems/library/extensions folder (very dangerous stuff, I know), sort of like what I was trying to do with the booting the audio kexts to get sound running in safemode (as discussed earlier in this forum). I was able to get things started in Safe Mode, which worked well for the next few months, but a few weeks ago, Safe Mode crashed as well, and everything I tried (with the exception of Single User Mode) resulted in a grey screen with horizontal lines across it (seemingly an indication of a hardware problem). I don't know if any of this means anything, but I thought I'd mention it.Īs a final (hopefully) update, the problems I was having with my G4 failing to start-up normally began to recur about two months after I had it serviced at a Mac retailer in Bangkok. When I do this, bang!, the entire machine revolts and I'm told to restart.
(Incidentally, quicktime runs without a problem, although it seems to drop frames, ie the playback is a bit chunky.) Also, the machine will crash (greyed out screen with the 'you need to restart your mac' message in four languages) when, in Finder, I have it set to column view and I highlight a video file, thereby creating a 'preview' of the video in the rightmost column. Strangely, iTunes will also quit if I try to change the view to CoverView. VLC media player closes as soon as I open it, and iTunes will close when I try to access any videos. The machine will force quit certain programs that use video as soon as I open them. Incidentally, I have begun to identify a pattern on the occasions when it does boot up properly. I got the test software from the apple site, here:Īs an update, I've booted-up in Open Firmware and reset the NVRAM, but unfortunately it didn't seem to resolve the issue. RobbertV, it only make the normal start up chime (or dong, or whatever). I've tried pulling out the 3rd party RAM I installed, but even with just the internal RAM, the AHT gives me the same invalid memory access message. The weird part is that the AHT readme mentions a control panel of some sort when the AHT runs, but all it get is white text on a blank screen, kind of like a terminal prompt. Invalid memory access at %SRR0: 00032ed8 %SS1: 003030Īnd then it gives me the option to 'mac-boot' or 'shut-down'. I did download a copy of the hardware test and burned it to make a AHT start up CD.
The big problem is that I'm currently traveling and I don't have my install CD/DVDs with me. I've done the fsck thing (no fixes needed). I've verified the harddrive (no fixes needed). It can only occasionally start up in normal mode - I get the normal grey start up screen, then either a blank blue screen with no cursor, or another grey screen with 4 or 5 lines all across it, or if I'm lucky, a proper start up. In order to fix the problem, you have to download some 3rd Party plugins, such as Soundflower, which enables you to choose a desired audio channel accordingly.My Powerbook G4 has recently been experiencing huge problems.
