Now that you've written down your display adapter
drivers we can continue to scan for unsigned drivers. To do this..
1) Click Start> Run> type sigverif in the Open: Line and press
OK.
2) Once File Signature Verification opens, click the Advanced
button.
3) in the Search Tab, select "Look for other files that are not
digitally signed." in the Look in Folder box type:
C:\Windows\System32\Drivers
4) Once you've filled out the location, click OK then START on
the main verification screen. Windows will then scan your system
and produce a list of drivers which have not been digitally
signed. Now click Close. The program will produce a log and txt
file of the unsigned drivers which can be found in the Windows
directory (C:\windows\) named sigverif.txt
5) Using this list, you can determine which drivers need to be
moved because they are unsigned. The purpose of this is to
determine whether an unsigned driver(s) is causing a problem while
in normal mode of Windows.
6) To test whether the problem is due to an unsigned driver,
we'll move all of the unsigned drivers to a new folder you create.
To create a folder, Navigate to your C:\ drive either using My
Computer or Windows Explorer and Right Click > Select New > Folder
and give it a name you'll easily remember (you may want to write
it down.)
7) Now that you've created a folder to move the unsigned
drivers to, we'll need to open another instance of My Computer or
using Windows Explorer, navigate to: C:\Windows\System32\Drivers
folder.
8) Using the list of UNSIGNED Drivers, begin selecting them and
moving them (Drag and Drop) to the new folder you created in C:\.
9) Once you've moved all unsigned drivers, restart again into
normal mode.
10) Test the program or function to see whether you still have
problems or receive the same error message. Note: Because most
driver files are associated with registry entries that haven't
been changed you may receive this error: At least one driver or
service failed to start...
11) If the problem/issue no longer occurrs, the issue was
likely caused by unsigned drivers. To determine which driver(s)
is the result of the problem, use either of the following.
Put drivers that are related to the same program or device
with the problem back into the
C:\Windows\System32\Driver folder then restart and see if
the problem reappears. If it does you'll need to continue the
test by removing the unsigned drivers again, restarting, then
adding one unsigned driver, restarting, testing the program or
device for errors and continuing until you encounter the error.
Once you've found the driver that is causing the error you
may elect to remove/uninstall it OR, disable the driver or
service.
To turn off a service,
1) Click Start > Run > type: %systemroot%\system32\services.msc
/s
2) A local services window will appear. Inside this window is
a list of all current local services and their status. The name
of the service is to the left with it's status to the right.
3) Locate the service which may be causing the problem,
double click it and in the Startup Type drop down list select
Disabled. Press OK and Restart.
To turn off a driver,
1) Click Start > Run > type: %systemroot%\system32\compmgmt.msc
2) The Computer Management Window will open. Click Device
Manager in the left pane. To the right will be a list of various
hardware. Locate the device in the list by expanding the
category it fits in. To disable the device, double click it. The
properties window will appear, from this window at the bottom of
the General Tab will be the Drop Down List for Device Usage.
Select "Do not use this device (Disable)"
3) Click OK and then contact the manufacturer of the device
for an updated driver for the device.
