Although I didn't really notice any significant increase in performance,
all seemed absolutely fine for at least a week. However, the PC then
started to play up - crashing and seizing up, rebooting, and also
failing to reboot (requiring a restart). I've restored the original
memory, and I'll have to see if the trouble persists.

Download and run Mentest86+ from http://www.memtest.org/ and run it
overnight. If it passes, download Prime95 from http://www.mersenne.org/
and run the torture test overnight. If that passes, the memory is most
likely OK.

It has been suggested that the problem might be that the 800MHz memory
is too fast.

Memory can't be "too fast". It can, however, be too slow (not rated to
run at the speeds at which it is operating).

It sounds as if you've been unlucky and your new memory has failed.
Running the diagnostics above will tell you.
