Subject: Issue 4 freezes in old age

I've had three separate Issue 4 BBC Micro Bs that all experienced this
problem, and I wonder if anyone recognises it knows the cause.

To begin with, the computer will run for hours just fine. One day, after an
hour or two, it will soft hang: pressing break will reset it but your
work/game is of course lost.

If you use the machine routinely, the time between hangs will decrease each
day until it's down to half an hour, and keep decreasing until it won't even
switch on -- it crashes during POST.

The longer you leave the computer without switching it on, the longer it
will run for between hangs. Leave it turned off a few weeks and it will work
again relatively normally.

Anyone know what causes this? Is there a fix?
