Just found this:



I swiftly changed it to never sleep. Let's see what happens....

I change the power plan so the PC sleeps in one minute. Here's what happened:



Seems the Win 7 default is to sleep after 30 minutes, not good for 24/7 BOINCing!

tomba, Can you please post the contents of your global_prefs.xml and global_prefs_override.xml files? They are found in your data directory, which is listed at the top of the Event Log around line 10, and is often C:\ProgramData\BOINC

Couldn't find 'em. Did a search on c: and I found them in c:\windows.old

tomba for the kernel times you go to the task manager, then the command bar shows you four options: File, Options, View, Help.
Go to View, and then the bottom, Show kernel times. This will show a red line in the graph and is below the green line.
Ideally the red line (kernel times) are low, if they are high (close to the green line) this is an indication of a (hardware) problem.
if its low, the 660 is okay. I guess it is in your case, as you have used it before in this system and many people use this card as well.

Perhaps you could Jacob Klein the files he asked for in the BOINC Data folder. He may help you better than I can.

This could be the source of your problem...
It's so self-evident that a PC used for crunching should be set to never go to sleep that I didn't thought of that (and I didn't find it in the FAQ topic). Sometimes I forgot to set it after reinstall, so I've made a customized Windows (XP x64) installation package with the necessary drivers and presets.

This could be the source of your problem...

Looking promising. After I set the beast not to go to sleep I observed the in-process Nathan long. It was 71% complete and 19 hours had elapsed since it was sent.

It just finished. The 29% unfinished was done in 3h33min. That's equivalent to 12+ hours for a full Nathan long so the GPU was running without interruption for 3h33min.

Now, if only I could get another Nathan long....

Good to hear it works now! Well.. actually this or similar issues are why I asked yesterday:

Does your machine run GPU-Grid 24/7?

Just in case you're being asked this again ;)

Scanning for our furry friends since Jan 2002

Just to confirm that I'm out of the woods :-)

This morning I completed a Noelia long that had run overnight. Run time was 11h:58min and elapsed time, from sent to reported, was exactly 13 hours (and the credit was a very generous 180k! Perhaps a little payback for the many failed Noelias these past weeks?).

Grateful thanks to all posters for your support.
