My machine was misbehaving again,
traced the issue to the PC power supply    ( it was ancient )

The symptoms if anyone gets the same, were  occasionally failed boot up  and occasional failure to run apps...  Once it was placing, it seemed to rum OK.

It seemed more like a corrupt disc, but despite various attempts to fix it, the problem persisted until I swapped out the PSU

These old machines take a bit of nursing sometimes.. !

On a similar subject - after my near-disaster with mains on the feeder serial port, I've just been going through & testing all the various spare bits I have, and noticed that some of the caps on the PC motherboard were bulging.
Not only that, the ones on the identical unused spare motherboard I had were the same!
3300uf caps, measured 1-15uF.
No obvious ill-effects but seemed prudent to replace them.
