I work nights and my Mac G3/266 Beige Desktop has run very reliably for over 2 yrs now. I generally go onto the internet after work.
I installed the OS 9.1 upgrade the day after it's release, and everything seemed fine. But lastnight I came home started up my computer and it froze upon loading extensions.
So I restarted, and got no display at all. Obviously there was power going to the CPU, the restart chime "chimed".
After several restarts, trying to zap PRAM, trying to rebuild desktop, I was still getting nothing. I attempted to start-up off my System CD and couldn't
By now I'm panicking, and getting a grim realization that there's a serious hardware issue. So I disconnected all my external devices, except monitor/keyboard/mouse and tried to start again, still no luck
Now I'm really panicking. So I openned up my computer and removed my Added RAM, and retail ATI Rage Orion Card. Tried to start off CD, still nothing at all. So I switched the location of my Hard Drive, and also hit the hardware reset button on the Logic Board.
After doing this I was capable of starting off the system CD but It was showing no Hard Drive installed So I switched the Hard Drive back to Bay 1 and restarted and my Mac was alive again bootable off the Hard Drive
I was then able to return all my added hardware to where it was before with no start-up problems. My guess is the hardware reset button fixxed the issue here, but I'm still totally confused why this happenned. Up to OS 9.1 I've never ever had this problem
