I have ceased receiving gpu tasks on this computer until I get this sorted. Any advice as to how I can fix this? I can provide information as needed. Thanks!

I'm only seeing two GPU workunits with Completed, Marked as Invalid. Statistically, that's not significant enough to worry about.

From what I'm seeing on computer 7589692, I have 3 gpu tasks which have run, and all three were invalid.

You are using a driver that is known to give problems on older cards:

Unless this has been resolved by Nvidia the best solution is to roll back the driver to about 320.xx Doing a clean install to remove your current driver. You can expect a couple of black screens and re-boots during the installation.

Rolling back the driver seems to have fixed it. Thanks!
