If so STOP and use the power button on your monitor when you walk away instead! ID: 54405 · Rating: 0 · rate: / Reply Quote

This is an Nvidia driver bug. With the most recent set of drivers after the display goes to sleep or something like that tasks can't run correctly ID: 54410 · Rating: 0 · rate: / Reply Quote

The beta 301.24 drivers do not have the bug. ID: 54414 · Rating: 0 · rate: / Reply Quote

I have endless computation errors despite having no screen saver. This is frustrating. It is not the screen saver but display sleep that is causing the errors. Update to 301.42 which does not have the bug. ID: 54518 · Rating: 0 · rate: / Reply Quote
