I'm running Einstein@Home, I've downloaded a large number of GPU works and only 3 of them finished computation, and others gives computational error.

Here is a few logs of one of the error:

9/3/2012 16:43:52 | Einstein@Home | Starting task p2030.20110929.G47.95+01.04.C.b3s0g0.00000_1736_2 using einsteinbinary_BRP4 version 122

It seems the application terminate in a few seconds and does not generate any output file. I notice that when I run some graphics-intense games(suspended GPU work), display driver crashes occasionally, would this be related? and will I need to RMA the display for a repair??

For my system spec:
CPU: i7 2600
Graphics: GTX 275, Driver: 295.73, Not overclocked (I can't overclock it as the tiniest overclock will quickly result in crashing display driver.)
OS: Windows 7 x64 Home Premium

By Running 295.73 drivers, once the monitor connected to the DVI port goes to sleep, the cuda device becomes unavailable,
eithier run a 290.53 or earlier driver, or set the Monitor not to go to sleep, and physically turn it off,

Claggy

So simply set "Time until turn off monitor" to never and turn monitor power off manually when AFK??
I'll give it a try, but I can only report tomorrow as it had crashed all my work quota today.
