Yes, things have moved on. Following the various posts here and
Giulio's suggestion to stress test the system under windows, I found
Hotcpu Tester which has about 6 hours of tests including arithmetic
tests. I tried the first one and it shut the machine down in about 5
mins.

I spoke to a fairly enlightened support person who agreed that it
obviously a h/w issue although he said 44 degrees is more likely to
refer to the system than the cpu. He confirmed the amd64 chip should
run 64 bit applications without a problem irrespective of the
operating system.
So it's back to Acer again for repair.

If it is repaired properly, it shouldn't be necessary.
Many thanks for everyone's help ;)
