I have a new rig, self built, but not by me. It runs Windows 7 and has 4GB memory so it's reasonably quick. I downloaded BOINC and got it crunching away and the settings are EXACTLY as they were on the old rig which crunched, non-stop, for over four years.

However, despite having it set on Run Always and Network Activity Always Available the crunching keeps stopping. In Messages it states " Windows has suspended computation, user's request" which is not the case. There is no obvious pattern to the stops and as soon as I click on BOINC it starts crunching again.

Anyone come across a similar problem?

And, any ideas what to do about it
