drivers not to be loaded in Safe Mode, but when this occurs in a normal startup, it alerts an
administrator to a possible source of a problem.

1.To isolate the problem to the network card, I would restart, press F8, and select Safe Mode
from the Advanced Boot Options menu. Being able to start in Safe Mode does not isolate the
problem to the network card, because that is one of several device drivers that aren’t loaded.
It does indicate, however, that one of the components that was not started is the cause of the
problem. To isolate the problem to the network card, I would again restart, press F8 and
select Safe Mode with Networking. This loads the networking components, including the
network adapter driver. If it fails to start in this mode, the problem has been isolated to the
network components. The most likely component is the network adapter. So, restart again,
press F8 and select Safe Mode from the Advanced Options menu. Once in Safe Mode, run
Device Manager, select the network adapter, and disable it. Restart once again, and allow it
to start up normally. If the start up succeeds this time, the problem is isolated to the network
adapter itself. Use Device Manager to perform whatever maintenance is appropriate. If the
driver was recently updated, use Driver Rollback. If it needs an update use the Update option.
If all else fails, uninstall the device driver and acquire a new driver or an entirely new
adapter.
2.Demonstrate the steps to your instruction. Do this by first restarting the computer in Safe
Mode, describing the reason for doing so, and then restarting in Safe Mode with Networking,
explaining that if this failed, it would prove that the problem was with network components.
Then, restart in Safe Mode, open Device Manager, and open the Properties of the network
adapter and discuss the Driver Rollback and Update options.

The two procedures in question are Refresh Your PC and Reset your PC. Refreshing is
less drastic, and is what you should try after trying other options, like System Restore. It will
leave you with your personal settings, but reset all system settings to the defaults. It will save
your data, as well as any apps purchased through the Windows Store. It will remove apps
installed from any other source. After a Refresh, a list on the Desktop shows all programs that
were removed, but all data files are saved.
The second procedure is much more drastic, because it removes your data and all installed apps.
