Recently I have noticed that the seti@home v7 7.07 (opencl_ati_cat132) tasks won't resume computing after my computer got reboot or recover from sleep mode. And the process always stalls at approximately 20%. Does anyone encountered the same problem like me?
my platform is intel core i7-2720qm, 8GB RAM, AMD 6470M GPU, operating system is windows 10 64 bit.[/img]
I have already installed the latest stable version graphics driver.

Now the problem becomes this:
application has been blocked from accessing graphics hardware
Does anybody encountered the same problem? How to fix it?

If by that you mean you don't see graphics on tasks running on the GPU, this is normal. Graphics are only available on tasks running on the CPU only. Perhaps that in some future that will change.

If you meant something else, please elaborate.

Can you please post the BOINC start up messages (CTRL+SHIFT+E)? The first 30 to 40 lines will do.

This is it. But I think it actually has nothing to do with all these messages.

You have your computers hidden, so this was the easiest way to get some information, like driver version and the actual computerID, so we can check what errors -if any- it throws.

Aside from you -seemingly- aborting tasks running on your GPU, I didn't see it throw any other errors. I see you tell BOINC to run with one CPU core less, so that core can cater for the GPU, that's good.

According to a search I did earlier, the error you get can happen when Windows 10 has a problem with the driver, it not being completely compatible with the hardware and Windows 10. This being Windows 10, I doubt you have much choice in the matter which driver you get, so it's probably the latest and greatest from AMD, Catalyst 15.7.1, but you could try to run with an older driver. Until Windows 10 decides you must run with the latest and greatest again, of course.

You could also try to clean install the present driver. Use a program such as Driver Sweeper to completely get rid of the present driver, then install the new one.

Message 1741265 - Posted: 11 Nov 2015, 5:22:46 UTC - in response to Message 1741153.  

I have almost tried every methods on google, but none of them can solve this problem. I also tried to modify the registry table, restore to previous version of graphics driver and clean reinstall of it.
Anyway, thanks for your help!:)
