Possibly a bad RAM Expansion board? Is it when you do a lot of work or run several apps/one large app at once?
The death chime could possibly be a residual effect of hitting a bad memory location and when you restart it notes the error?
I am not sure what you could use to check the RAM, but try booting it, making a RAM Disk using as much memory as possible and copy files to try to take up that whole RAM Disk. if it fails in the middle of the copy/freezes it's possible you have a bad RAM Expansion board.
It's a possibility but I ran into that with a 3400c 64MB board. It was like at the last 1MB of the area and found it buy creating a RAM Disk and copied all the way up.
TechTool Lite confirmed it was bad so I had to get a replacement.
Too bad it's on it's way out though. Something in the video circuitry is going and it has artifacts in it. It will ghost images are artificact when running applications. no matter the res/colors. lower bit color schemes help, but I think the VRAM is bad on it.
Either way, I would try that method, or try to get an OS on it that can do virtual memory, create as much virtual memory as possible, use a RAM disk that would cause your system to use the VM space for the system swap, then fill up the RAM disk. that will allow you to find it easily.
