How to fix Blank Device manager

RESOLUTION:
==========

----------------------------------------------------------------------
CREATE A RESTORE POINT BEFORE ANY OF THESE STEPS
----------------------------------------------------------------------

STEP 1:
======
Check if Plug and Play service is started.Check the settings of the same in the
registry

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PlugPlay

ImagePath = %SystemRoot%\system32\services.exe
ObjectName = LocalSystem
PlugPlayServiceType = 3
Start = 2
Type = 20

STEP 2:
======
Advanced cleanboot (316434) and Hardware cleanboot (SOX051008700004)

STEP 3:
======
System restore (306084)
If we know when the issue started, read the system restore point information for
that day prior to trying the restore

STEP 4:
======
Look for the update KB905749 and try uninstalling it. Be sure to shut the system
down and wait 10 seconds before restarting.

STEP 5:
======
Go to safe mode - check for bangs in hidden devices in System devices - Uninstall
PnP BIOS Extension and any other device having a bang

STEP 6:
======
- Follow SOX041029700032
check the permissions on
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_RASAUTO
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_RASAUTO\0000
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_RASAUTO\0000\Control
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_RASMAN
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_RASMAN\0000
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_RASMAN\0000\Control
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TAPISRV
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TAPISRV\0000
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TAPISRV\0000\Control

If Administrators is listed, then remove Administrators. The default permissions
for these keys are:

System : Full Control : This key and subkeys
Everyone : Read Only : This key and subkeys

Change the permissions so that they apply to "This key and subkeys" and not just
"This key only".

STEP 7:
======
We could try to register the following files
regsvr32 devmgr.dll
regsvr32 dmocx.dll
If the files are missing, extract a copy from Windows XP CD-ROM or the
ServicePackFiles folder

STEP 8:
======
Copy the following on a notepad.Save it as dev.reg.Double click on the same.Restart
the computer.

Every time I login my facebook account,it gets successfully login but the home page as well as I can't see anything in my account,I am suffering with the problem for last 7 days


Issue: Every time I login my facebook account,it gets successfully login but the home page as well as I can\'t see anything in my account,I am suffering with the problem for last 7 day.

Cause: May be a virus infection, Software conflicts of web browsers and maybe change in browsing settings

Resolution:

1) Create a System restore point as backup so that you can return back to the present settings if required.
Note: This is for a precautionary measure.

Steps to created System restore point:

1.
Click Start, point to All Programs, point to Accessories, point to System Tools, and then click System Restore.

2.
On the Welcome page, click Create a restore point.

3.
On the Create a Restore Point page, enter a descriptive name for your restore point, and then click Create.

****************************************************************************************************************
2) Try using different web browsers such as Mozilla firefox and Google chrome to see if the issue is with any one browser

******************************************************************************************************************

3) If so and issue only with IE, try resetting the IE browser.

Steps to reset IE.

Find tools option in IE and the internet options in that and select it.

In the Internet options select advanced and find the reset button and click it and press ok.

This should work.

*******************************************************************************************************************

4) If the second step does not work, try reinstalling the Adobe flash player.

You can get Adobe flash player in below link:

*******************************************************************************************************************

5) If neither of it does not work, then you need to restore the system to an earlier date when it was working.

Click Start.

Point to All Programs.
3.
Point to Accessories.
4.
Point to System Tools.
5.
Click System Restore.
6.
Follow the instructions on the wizard.
Creating a restore point can be useful any time you anticipate making changes to your computer that are risky or might make your computer unstable. If something goes wrong, you select the restore point you just created and Windows XP undoes any system changes made since that time.

2.
Click Create a restore point, and then click Next.
3.
In the Restore point description box, type a name to identify this restore point as seen in Figure 1 below. System Restore automatically adds the date and time that this Restore Point is created.

• To cancel restore point creation and exit the System Restore Wizard, click Cancel.
To view or to return to this restore point, from the Welcome to System Restore screen of the System Restore Wizard select Restore my computer to an earlier time. Then select the date you created the restore point from the calendar in the Select a Restore Point screen.
