Ladislav Cermak's post on October 18, If the driver update history page doesn't reveal anything, it is time to check out the Device Manager. Type device manager in the Start Menu search bar and select the Best Match. Check down the list for any yellow error indicators. If there aren't any, it is unlikely a driver is the source of the issue.

Unfurl the Network adapter section, right-click the driver for your Wi-Fi adapter or Ethernet adapter or both , and select Update driver. Now, select Search automatically for updated driver software, and Windows will automate the process for you. The network adapter section in your Device Manager probably won't look as busy as mine, so it should be relatively easy to figure out which adapter to choose. If updating Windows 10 doesn't work and updating your driver fails, you can always opt for a clean installation of the driver.

That means that you delete the driver from your system, then install the latest version without assistance from Windows. As this relates to your network adapters, you need to download the correct driver ahead of time, as after you delete your network adapter driver, your internet connection may cease to work.

Head back to the Device Manager and unfurl the Network adapter section. Now, copy and paste the driver name into an internet search engine. For example, I would run a search for "Realtek pcie gbe family controller" to find the latest drivers for my Ethernet adapter. Browse to and download the latest version of the network adapter available for your hardware.

Most drivers come with an automated installation file named setup. Once you have the correct network adapter drivers downloaded, you can go ahead and uninstall the existing network adapter driver.

In the Device Manager, right-click your existing network adapter driver and select Uninstall. Use ln list nearest symbols on this address to see the name of the function. Typically, when this error occurs, a driver has tried to access an address that is pageable or that is completely invalid while the interrupt request level IRQL was too high. This can be caused by:. You can use dx display debugger object model expression , a debugger command, to display this: dx KiBugCheckDriver.

The function was marked as pageable and was running at an elevated IRQL which includes obtaining a lock. If the problem is caused by the driver that you are developing, make sure that the function that was executing at the time of the bug check is 1 not marked as pageable or 2 does not call any other inline functions that could be paged out.

The following example is output from! If a trap frame is available in the dump file, use the. To start debugging this type of bug check, examine the stack trace by using the k , kb , kc , kd , kp , kP , kv display stack backtrace commands.

In the debugger, run the! For example:. In the majority of cases of this type of bug check, the issue is not the IRQL level, but rather the memory that is being accessed. Because this bug check is usually caused by drivers that have used improper memory addresses, use parameters 1, 3, and 4 to investigate further.

Use ln list nearest symbols with parameter 4 to see the name of the function that was called. Also examine the!

Use the display memory commands to examine the memory referenced in command in parameter 1.
