hi, i returned recently to the " boinc " volunteering " crunch " with gpugrid

and

worldcommunity grid using new hardware with nvidia gtx980 and win10-64bit,

started investigation what cause it might be that stops the crunch of gpugrid, i

often had to restart the client and it afterwords would work fine,

i used to let the screensecurity appear after 10 minutes of no input

suspected that screensecurity was involved and yes, no more stopping worktask

gpugrid, i closed the appearance of the security window ~ the client is working

fine with raised clockspeed of the gtx980
