So, I seem to have the common IIci issue of the machine spontaneously shutting down. Mine is configured, as follows:

System 7.5.5

128mb RAM

2gb Quantum Grand Prix 7200rpm

Radius PrecisionColor Pro 24x

AsanteFast 10/100

FWB JackHammer, currently connected to nothing

I had assumed that the problem was either the PRAM battery, or the PSU. So, when replacing the PRAM battery did nothing, I replaced the PSU with a known-good unit from a 7100, to make sure that I had sufficient VA. Neither seems to have done the trick.

In my case, it does take quite a while for the machine to decide to spontaneously power off. It's usually over an hour, which is about the time that I always think I've fixed the problem.

I don't see any obvious failed caps on the board, but I'm not an expert.

Any ideas?

Thanks!
