.... and please while installing and connecting the software, do not overlook that little box just before the field where to enter name and password to indicate you are an 'exisitng member'. That will walk you right in.

Without knowing more about the OS, memory and disk space, perhaps that laptop just got too hot for comfort. Airflow in most of them is poor for extended use.

Simply raising it on a metal pie rack, getting one of the thermal fan coolers to sit on and/or opening all of the drawers/ports can possibly help.

There's a BOINC throttle, but it's rather rough and not as smooth as the old UD throttle. Some have managed to make BOINC slow down with Threadmaster, but it's a techie solution. My desktops run at 100% 24/7 so I don't worry about it here.

Thanks for your help
