Hello recently my WUs are failing when I lock my computer. It seems to be happening just with GPUgrid as far as I can tell. My GPU card is Quadro K5000. Has anyone an Idea what the problem could be and what solution would work (except not lock the PC)?

Thanks

Do you use Windows Remote Desktop while your computer is locked?

make sure you don't ever go to the user selection screen, never use "switch users". I always disable fast user switching on my win7 machines. windows vista/7 switches to the microsoft default video driver at the user selection screen and that kills anything running on the gpu.

I do not use the remote desktop. But i do have windows 7 64bit and I will try to disable the fast user switching.

Thanks

Hello,
I disabled the fast user switching but I still got the failling WUs.
And just to prevent questions that might coming the GPU or CPU is not overclocked.

Hello skgiven,
you may be on to something I usually also turn off the monitors when I lock the PC. And yesterday (to make something different) I turned off the monitors without loocking the PC and I got the erros also.
But it is not the sleep mode you where refering. The sleep mode is already turned off. I allways turn off the monitors using the power buttons.

Could there be a problem with the premium mosaic modus I use?

for the driver yes I use nvidia 320.27 and I will try an advanced clean install.

Thanks for the threads I will check it if there will be a solution for my problem.

Hello ExtraTerrestrial Apes but the 320.27 driver is a WHQL driver.
