OK, I've checked all the fans and no problems there. The RAM seemed to be in place ok, but I took them out and put them back in and repositioned the clips to be sure. Couldn't take the sound card off. I currently cannot keep the system running for long enough to run the RAM test u suggested!
Thanks

You have to do some swapping at some point. For work on home computers, it
helps to have more than one computer.
For example, I would move the (suspect) RAM to another computer, and test it
there.
If the RAM tested good, another frequent point of failure is power supplies.
I would measure the rail voltages with the (suspect) system intact and running,
using a multimeter. You can probe the back of the main connector, to get a
sample of each rail. 3.3V, 5V, 12V, +5VSB, should all be within 5% of their
nominal value. (-12V is there too, but may not affect stability. It gets used
for things like an RS-232 port.)
If that was too complicated, I would just swap in a known good supply. If
still no good, you might suspect a motherboard problem.
Processors are generally pretty reliable, and would not be high up on my
list of suspects. Modern processors are protected against extreme overheat
(THERMTRIP), so aren't likely to get damaged by having the heat sink fall off.
If possible, I like to encourage testing first, to try to eliminate any
unnecessary swaps. If you are totally blinded, and cannot collect any
test results at all, it just means more swaps until it works. On one
of my earlier computers, I replaced almost everything, so I know what
that is like. Sometimes you get lucky, and sometimes not so lucky.
