HP2 computation errors

[Sparky]

I don't think Windows updates have any impact on errors. What I do know, however, is that shutting down or rebooting your computer too quickly can cause errors. This was a problem with Vista which has a tendency to shut down very fast. I have one computer that runs Vista. I always make a point of exiting BOINC first, then waiting ten seconds before rebooting.

Yeah Vista's fast shutdown would trip up F@H on my GPU all the time as well. At least it usually would restart where it left off but not always.
