That's true, but I dont think he said the HDD is clicking

When I had the same problem I narrowed it down to memory, it turned out to be overclocked memory causing constant restarts downclocking it slightly resolved the issue.
I have also recently fixed somones computer which again was narrwoed down to memory causing the problem however it turned out it was a faulty 1GB stick causing random freezes.

What I'm saying is most porblems are with the memory but specifiaclally is hard to say what it is.
