BOINC message saying I have two Winstein accounts and I need to delete the old one. But, I can't, because the remove project bu

Great!  I'm sure you'll do just fine.

The notice is NOT telling you to remove the project.  It is telling you that you are attached twice (ie. two different URLs) and that you need to remove the wrong URL.  The reason why you shouldn't even try to do that is that the URL being suggested for keeping (einstein.phys.uwm.edu) is not the correct URL to use.

To get to the bottom of this you need to answer the question, "Are you using an account manager like BAM for example?"  Alternatively, are you using the boinctasks app?  Apparently, it can create the same type of problem.  Once you tell me that, I'll send a PM to Richard Haselgrove who actually (I believe) maintains the official list of all correct project URLs and see if he has any suggestion on how best to solve this.  Richard made the 2nd post in that thread for which I've already given you the link.

I had a look at your Windows 10 machine on GPUGrid.  I know nothing about that project, but I seem to recall someone mentioning at one point that all their applications were for GPU crunching only.  I could easily be wrong. Your host over there is listed as not having a GPU.  Perhaps that is why you can't get any work?

If you set NNT the button changes to read "Allow new tasks" and the status column on the projects tab for BOINC Manager shows that the Einstein project won't get new tasks.  I believe it's impossible to get new tasks after that condition has been properly set.

Once any task has been allocated to your computer, it's no longer a "new" task.  If that task gets lost for any reason (ie. not aborted properly, not a comp error, not returned, but somehow just lost), the project will resend a copy as a 'lost task'.  If the project sends a lost task and you don't want it, just abort it and make sure to click update so the aborted task can be reported back to the project..  Sometimes people abort tasks but don't report them.  The tasks will expire after two weeks but if the host (perhaps with a new BOINC install) contacts the project before they expire, they will be sent again as lost tasks.  If this happens, just abort and report.

I think you would know if you have installed BOINC Account Manager (BAM).  Please have a look at this page where account managers are explained.  There is a link there to the Boinsctats website where BAM is available.  Did you ever install that account manager?

 With regard to GPUs, yes all machines need a GPU of some description just to draw on the screen.  Some GPUs are internal to the CPU chip and may not be powerful enough to handle crunching jobs.  You may need to install particular drivers to unlock any crunching ability.  In your particular case, your GPU is an Internal one and is described in the entry for that host in your list of hosts at Einstein.  I also see that your list has gone down to 4 so you have managed to merge two of them.  I don't know why that GPU doesn't show on the GPUGrid entry for that host.  You would need to ask over there.

GPUGRID GPU tasks run both on my Windows 10 PC and my main Linux host. Quantum Chemistry tasks run on both my Linux boxen, not on the Windows 10 PC.
