Device Manager empty and Windows Explorer>My Computer window is slow

  1. I've recently run into a problem where the Device Manager is empty, and any time I try to view the Explorer window (or click on the My Computer in an explorer window) it's painfully slow. It's also prevalant in Word or any program where you search for a file to open. In safemode however, she's fast as a rocket, but still no Device Manager content.

    I've tried the SFC /SCANNOW, I've tried REGSVR32 DMOCX.DLL and DEVMGR.DLL.

    Anything else? Spyware is showing up blank, and I've also run the APROPOSFIX in Safemode. Found nothing.

    Apart from running the repair function, I'm curious to see if it's still spyware but I'm doubtful now. I thought it was TweakXP or IE7 Beta 3 that caused some of this wonkyness - and I can live with the slowness but not with an empty device manager.

    I've searched this forum, most of it has been the aproposfix or a sfc /scannow worked fine.

    Thoughts guys?

    - Goto Add/remove programs, uninstall any programs you dont use any more
    - Clean out your hdd, backup data files you dont use regularly to cd/dvd etc
    - Clean out your startup/bootup programs, and any programs you use in the background
    - update drivers, windows updates, etc
    - do a chkdisk /f and a defrag
    - check for viruses and other warez etc by going through this sticky: and pasting the HJT file as a .txt attachment in the Security and Web forum

    Specific troubleshooting
    - Any environment changes recently? hardware/software?

    Blank Device Manager is one of those perennial problems,for which there is no one answer.
    Sometimes logical systems just get too complex.

    There is a compilation of solutions HERE. I prefer this one,myself -

    This issue seems to be related to missing permissions in the registry.

    You must use regedt32.exe in Windows 2000/XP AND be logged on as the local administrator to perform this task:

    1. Go to Start, Run, and enter regedt32 and select OK
    2. Maximize the HKEY_LOCAL_MACHINE window.
    3. Scroll down to SYSTEM\CurrentControlSet\Enum
    4. With Enum selected click the Security option from the Top of the screen then the Permissions menu.

    Note: At this point you will probably notice there are no permissions on this key.

    5. Click Add
    6. Add the group Everyone and the user SYSTEM
    7. Select Everyone and check only the Read box
    8. Select SYSTEM and check Full Control
    9. Click the Advanced button at the bottom of the window.
    10. On the Advanced window check Reset permissions on all child objects
    11. Click OK
    12. On the warning window click Yes
    13. Close REGEDT32

    Re-boot the system if necessary and then check the device manager to see if everything is showing now.

    If not, then Click start, select run, type services.msc in the run box, hit your enter key.

    Look in the list of services for Plug and Play. If plug and play is turned off, device manager won't list any devices and of course, most of your devices like a printer connected to USB wont work.

    If it is turned off, right click it and select start.

    There are also a couple more HEREand HERE

    Thanks for posting those suggestions: already looked into the registry. The services are also all fine, and the registry is set properly.

    Looks like I'm off to do a repair...ugh...

    As a final suggestion downoad CCleaner run it,then use the start up manager in Tools to disable eveything.
    It also has an Add/Remove utility.

    Feel free to post an HJT LOG.It would help to rule out the spyware possibilty mentioned in your first post.

    I will note that when the PC is in safemode, the windows explorer is back to normal speed. yep, have CCLEANER. Great app.

    Your log is clean, unfortunately. :)

    Did you try disabling all the start up programs except Firewall/AV. ?
    If explorer works in safe mode,then the problem must be a start up process or device driver
    of some sort.

    Explorer freezes usually have one of three causes -

    1.A faulty shell extension put in the right click menu.Known culprits include Divvx,Spysweeper.

    2.The presence of .AVI files and Divvx.

    3.The My computer folder sometimes hangs if there is a faulty/wrongly connected drive.
    CD/DVD, USB ,HD etc

    I`m hoping the Device Manager problem might be related to the Explorer problem.

    BTW get rid of Norton.It`s a bloated and troublesome program.
