Whilst looking at the girlfriend's parents PC which was "going slowly",
amongst the masses and masses of spyware I also decided more RAM above
the 256MB in there wouldn't go amiss (with all the stuff they use,
memory usage in WinXP is usually near double that).

However, when I opened up the box I noticed that around 10 of the caps
on the motherboard are bulging to the point of leakage on the tops.
Looks to have been the case for some time but they've not had any probs
bar the system being slow (which I'm attributing to the spyware and lack
of RAM). System is from 2003, so looking at 4 or nearly 5 years old.

If I don't replace the motherboard now, what are the implications? It's
becoming one of those "wish I'd never have opened it" things...

Easiest thing to do is add more RAM and then leave it til they start
seeing sudden freezes or shutdowns.

If you want to do something about it, and you have a spare dead mobo
or another source of appropriate caps: Take the machine apart, either
desolder the dodgy caps and replace (make sure you resolder the new
ones right way round!) or use a chunky set of snips to take the dodgy
caps apart leaving the wires in the mobo, and solder new caps to the
wires. Capacitor innards aren't very healthy to be around, so be ware.

Or buy a new mobo. Trouble is with a machine of that age is that you
either get a secondhandy replacement with similarly-dubious caps, or
have to replace mobo/cpu/ram/video all at once. At which point you
might as well get them to buy a £300 Dellish box or (to be kinder and
avoid standard malware infestations) a Mac Mini.

I've a vague idea I owe you a favour: I've got a bunch of caps I could
get over to you, salvaged from dead-from-other-reasons mobos. Want?
