Please post the Boinc startup from the Event Log, the first 20 to 30 lines will do, it'll give us a glimpse of what OS it is on, and how you installed it: http://boinc.berkeley.edu/dev/forum_thread.php?id=8600#50407 Claggy ID: 51364 ·

Because I noticed in the full log, that this log entry also appears once before I updated Boinc, and that's the only other thing changed. So it might be a problem with GeForce R331 Game Ready Driver 331.82 - WHQL ID: 51366 ·

Have you been trying to use Remote desktop on that host? (I would have expected Boinc 7.0.28 to say the GPUs have become unusable) Please confirm that the Monitor is connected to one of the GTX 660 and not to it's internal GPU. Claggy ID: 51369 ·
