Desktop disappears after switching GPUs RRS feed

  • Question

  • HP Pavilion dv7 running on Windows 7 64-bit;

    Oftentimes when the GPUs automatically switch due to power sources, all desktop icons disappear, and I can't right-click the desktop. Hitting the show desktop button doesn't help, and restoring the desktop through IconRestorer doesn't work either. Thanks in advance for any help.

  • Hi,


    “all desktop icons disappear, and I can't right-click the desktop. Hitting the show desktop button doesn't help”


    I wonder whether you try to use  WinKey +D to show desktop? It looks like explorer.exe was hang at that time. You may try to end the process of explorer.exe, it should be restart soon. If it works fine after restarting, we can verified the cause.


    Also you may use Process Explorer to collect the some information about explorer dll files, then we can analyze the log to find some clue:


    1.       Download the Process Explorer form the following :


    2.       Run Process Explorer, click Agree to open it.

    3.       Click View on the Tool menu, and select “Show Lower Pane”.

    4.      Click View on the Tool menu, click “Lowe Pane View”, and select “DLLs”.

    5.       Try to repro this problem.

    6.       Find the process which occupied a great quantity resource.

    7.       Then highlight the process in the left pane.

    8.       Click File in the Toole menu, and then select “Save As…”.

    9.       Save and upload it via SkyDrive, then post a link here.




    I suggest that you may try to run Windows 7 in safe mode then check the problem again.


    If the issue disappear in safe mode, please upgrade the graphics driver. Then check this problem in Clean Boot to narrow down whether a third-party software caused this problem.




    Note: Clean Boot is a step of troubleshooting, we can go back to normal by running MSCONIFG.


    If this problem disappears in Clean Boot, you may use half and half method to ensure which software caused this problem.


    Hope that helps
