This work unit caused it http://setiathome.berkeley.edu/result.php?resultid=1112701831

Once this happens it appears (not consistently) that subsequent WU's also fail. I saw this first on the beta seti cuda project. I switched to regular seti a few hours ago, but after just 1 good WU I got this one. I rebooted just to be safe and am back running gpugrid. I do not see this problem (the display driver reset) occurring in gpugrid.

Vista 64, gfx280 180.84, BM 6.5.0

From event log 
Display driver nvlddmkm stopped responding and has successfully recovered.

Since you are using a beta version of BOINC, you may want to report this on the BOINC Developers list.

Discovered that when the driver gets reset, my VNC server loses its display. I can log in remotely, but cant see anything as the display is black. When I get back to work (or get home) the display is all fuzzy and pixelating. This was on Ultra VNC and YMMV for other VNC flavors.

The task example error you gave is a common one with CUDA and Very Low Angle Range or VLAR WU's "WU true angle range is : 0.012636". It's suggested that you abort these since it's not likely you'll be able to complete them. It's a bug in the CUDA app they're working on.

There is a batch file you can create to spot them before they start so you can abort them. There's info on it in this message
