First I guess I should introduce myself, as I'm new to the list. I'm Joe, and I use a 2400c, which I've had for almost 4 years. I'm also a former Duo (280c and 2300c) user, and although I only recently subscribed to this list, my brother used to be a member, and I think this is probably how he put me in touch with the guy who sold me my 2400 2005. Anyway, my 2400 has been entirely reliable until I started monkeying with it. about a year ago I misdiagnosed a sudden battery failure as a bad power board, and replaced the power board with one that failed a couple months later. D'oh. Then I took it apart again (several times) a couple months ago to install a G3 upgrade and bigger hard drive. The first time I got the GLOD, and no PMU/PRAM reset attempts would cure it. In hindsight I should have just unplugged the PRAM battery when I did the upgrade. But I ended up taking it all apart again to swap in a spare logic board, which worked fine with my G3 upgrade--hard to say if there was really anything wrong with my original board, or just a fluke. But then the (upgraded) hard drive refused to boot while I was on vacation a couple weeks ago. I was able to rescue some files via SCSI disk mode, but nothing Norton could do would make it boot, and when I tried to reformat it via SCSI disk mode, it just crashed the computer it was hooked up to. So I took it apart again yesterday to put the old hard drive back in, and ended up doing so twice, because I initially installed the wrong hard drive. D'oh. And now it's crashing left and right and is completely unusable. Is this what a NewerTech G3 does without the special drivers installed? Bad memory? I'll get Error 10s on startup, or shortly after getting to the desktop, or a "the Finder doesn't have enough memory" dialog I haven't seen before that includes only a restart button, and sometimes the big smiley Mac OS face will stay on the screen when the desktop is displayed following startup. I'm also getting a "built-in tests have found a problem with the cache memory" error that would worry me except that I know I've seen it at least once before since I installed the G3 upgrade, and I'd like to think it's just a symptom of not having their drivers installed (but now the thing is too unstable to install the drivers). Any suggestions? Thanks, Joe Elliott -------------- next part -------------- An HTML attachment was scrubbed...
