Many, if not most, of my projects' tasks do not finish. They either get a computation error or, strangely, stop counting DOWN and start counting UP until they either hit their maximum time limit themselves or I abort them after they become several days overdue. This also causes other tasks to abort because their due date has passed and they haven't started. This did not used to happen.

I am running an HP Compaq CQ50-135 with 32-bit Windows 7, 2GHz Intel Celeron CPU, 4GB RAM (2.91GB useable), 139GB HD (59GB free). To prevent overheating, I have a cooling fan platform on which my laptop rests. I even set the priority for the tasks to Above Normal, but it seems to make no difference whatsoever. I have the latest release of BOINC (v6.12.34) installed. I have attached to 30 projects, of which 5 are currently running or waiting to start. I let my system run all day, every day, except for the occasional reboot after a major Windows Update.

I also participate in Stanford's Folding@Home project, and it is extremely stable, so I am at a loss for what would degrade BOINC's performance. I never run Folding@Home higher than Normal priority, and I always run BOINC at Above Average or High priority.

Please advise if there are any settings i should consider modifying.

Do you run Folding at the same time as BOINC? If so, both on more than one CPU?
Which projects have work to run under BOINC? What are your caching settings?
