I am wondering if anybody else is having this issue. The last BIG update for windows 10 seems to have done something (I believe because that's when this happened). After the update to the operating system I get this message on Boinc Manager:

Of course this is not possible because I have been running the GPU ever since I started the project I'm on. Can anybody clue me in as to what has happened here?

FYI: the video cards runs just fine when Playing games so I have ruled out a hardware issue.


Rich.

Please post the first 40 or so lines from your BOINC Event Log (CTRL+SHIFT+E), including it showing what your BOINC is doing, which project tasks it is running.

Furthermore, see When requesting help... about what else we may need. In this case it would be nice to know what GPU you expect to see and which drivers you or Windows installed.

There seems to be a lot of it about, especially at MilkyWay. See

Jord - Thank you for the tip. I will provide whatever I can in this post and if there is something else you need let me know sir.

It wont let me copy and paste project tasks....is there another way I can do this?

The GPU is a Nvidia Geforce GTX 650 (which the Nvidia Geforce manager detects)
Driver version is: 358.91 - and is the latest.
operating system: windows 10, version 1511 (Latest BIG update, which "reinstalled" the whole operating system).

Lets me know if there is anything else you require.

Rich.

Thanks for the redirect Richard. I will see about getting some assistance there if Jord cant help. Thank you again.

Driver version is: 358.91 - and is the latest.

I was asking for the startup messages, starting from "Starting BOINC client hupsaflups", but all right, let's leave it for now. I'm assuming you didn't change the install to a service install overnight.

Which leaves those drivers, installed by Windows I presume?
Always, when having problems with the GPU going missing after you or the OS installed new drivers, either uninstall the new drivers and clean install them, or uninstall them and go back to the working drivers you had before. Also always get the drivers from Nvidia, not the ones offered through Windows Update.

The trouble with Windows 10 as I understand is that it will at times force you to use the drivers it finds are best for the system, and until Microsoft gets it into their heads that this isn't wanted by the user force, the only workaround here is to uninstall them each time, reinstall the previous ones and tell Windows you don't want to auto-update these drivers. And then hope Win10 allows that for the next fortnight.

The other people encountering the same problem at Milkyway had the same combination. If that's a part of "The big update" (who said they weren't issuing service packs any more - that one was 4 GB, I think I read), then we're going to get a lot of 'Needs OpenCL, hasn't got' reports.

Driver version is: 358.91 - and is the latest.

359.00

No sign of any OpenCL fixes in the release notes, but let's hope it does the trick.

All of you....thank you for your support. I did check the driver in device manager as well as the one in GeForce experience manager and they look both identical. They are both from NVidia. Although I will uninstall the driver in the morning and reinstall it again and see if that fixes the problem. I have made no changes to any services directly by me as I just let the operating system take over the installation of the updates by Microsoft. I did read after Richard provided me the link that it looks like some people are having the same issue as I am. I will have to investigate this further if I cannot resolve the problem.....maybe even shooting an e-mail to Microsoft about there update installation but I see that probably wont do much but Ill look. Anyway thank you all for your support.

Rich.

Jord, Richard, and everybody else. Removing all NVidia drivers along with the NVidia experience manager (which I probably didn't have to do) and then reinstalling everything from NVidia back again seems to have did the trick. Boinc Manager is now detecting the video card correctly and is using the processor on it once again. Something to remember the next time around. Thank you once again. I will relay this message over to the other message board for the Milkyway project.
