My computer must have restarted during the night. Upon restart the BOINC manager says GPU not found. I stopped the BOINC manager and reinstalled the Graphics Card progam Catalyst Control Center. Restarted BOINC and the program found the GPU and restarted calculations.
I have had previous issues with having to reinstall the Catalyst program which I thought were resolved in this thread: http://www.worldcommunitygrid.org/forums/wcg/viewthread_thread,34498 Why is this happening and what can be done to prevent it from occurring again? Catalyst Control program: 12-10_vista_win7_win8_64_dd_ccc_whql_net4.exe Windows 7 x64 Sapphire HD 7850 2gb |

Are you running on Windows or Linux? I know that with Linux, it simply is necessary to restart BOINC manually after each reboot in order for it to recognize an ATI GPU. The "sleep" trick that solves that for Nvidia cards doesn't work with ATI cards.

You have done everything I would recommend, but try the 12.11 beta 11 drivers. They are faster at HCC anyway. But I use the non-.NET 4.0 version; maybe that is causing some of your problems?

It's a Windows 7 x64 machine.
I don't see a version of 12.11 Beta without .Net 4.0 support. Also don't you need .net 4.0 support? |

I don't see a version of 12.11 Beta without .Net 4.0 support. Also don't you need .net 4.0 support? It is the "Latest Beta Driver", next to the bottom. I don't need .Net 4.0 support, on Win7 64-bit also. I think that is just for certain features for the Catalyst Control Center, which I don't install anyway (just the graphics drivers and the SDK, for the OpenCL drivers). http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_vista64.aspx |

I recently had the same problem, or at least something similar. On a reboot, the whole system would hang. I suspected the Catalyst drivers since the CCC icon would not appear in my system tray and I could not even invoke it. I finally had to do a clean install and that solved the problem.
----------------------------------------But I spent hours trying to resolve the issue short of doing a full reinstall including uninstalling and reinstalling drivers, pulling out the cards, etc. Nothing worked. In my case it all happened after I got a message that my version of Win7 enterprise was not genuine. I entered a new activation code which it found acceptable but the problem was never resolved until the reinstall.   |

Found it and installed:
AMD_Catalyst_12.11_Beta11.exe without the Audio, transcoding, drag and drop, which I don't think I need. I wish I knew the answer as these problems can be frustrating. Looks like all the steps I took in that other thread were not necessary to get BOINC to work under GPU. Just uninstall the CCC drivers, reboot and reinstall the CCC drivers and restart BOINC. BOINC seems to automatically find the OpenCL and run the GPU after this. I'm giving the Beta version a test to see if it is any different. Also I'm curious if it will run HCC any faster. If the beta version is supposed to be about 10% or more faster then I should see a decrease of 30 seconds or more between HCC results under the different drivers. Right now I don't see it. |

It happened again.
I restarted my computer and BOINC said my GPU was missing. Stopped BOINC. Reinstalled: AMD_Catalyst_12.11_Beta11.exe (without Net) Restarted BOINC. GPU Found and running normally. Anyone have any thoughts? Why does a restart cause the GPU to not be found by BOINC? BOINC 7.0.28 x86 Win7 x64 SAPPHIRE HD 7850 2gb |

I know I've said this already, but if this is a dedicated cruncher and not a personal use machine, the easiest thing to do is a complete, clean reinstall of the OS and drivers. That's what I had to do.
----------------------------------------The full catalyst install package, if you stop to select the "custom" install option, you will see that there are a variety of other things being installed besides the driver, any one of which may be causing your problem. |

@Nevada Bob: Same happened to me about a year ago, I had to reinstall Catalyst on every boot to keep the GPU crunching running.
The advice I got was to uninstall the old drivers completely before installing the new ones - the Windows control panel uninstall, reboot, install new drivers, reboot. It's a while ago, so I no longer remember if that's what fixed it - I reinstalled the OS from scratch a bit later too. It works now, anyway. |
