I think I may have discovered a possible problem and maybe a reason for these BSODs, however, I'm not sure why it's happening.

Looking at the processes I was concerned that Services.exe is taking up a whopping 645MB on startup (private bytes).

Process explorer shows page faults constantly occurring. After a few mins the count is around 1.3 million and going up at the rate of about 5 per second.

Any ideas what might be the cause of this? It certainly doesn't seem right to me and checking my laptop shows that services.exe is taking up a conservative 3MB of memory.
