I was looking for a fix on this foum and now that I found the solution wanted to let other future searches know.
If when rendering a project your machine shuts down (crash):
a) test your system with PC tools like memory/hard-drive/CPU/motherboard
b) try taking out your memory and reinserting (mybe change slots)
c) test for heat (the CD with your motherboard should have some utilities)
d) Use canned air and dust your system.
After the other tests, this last one did it for me. The CPU fan had a coat of dust blocking heat in the CPU.
Also I had the sides of the case open (not always good as air sometimes will not circulate).
