Troubleshooting

For most PCs, the installation of this new driver will be trouble-free. Oc- casionally, however, it may be necessary to update the driver or remove it entirely and re-install it several times in order to make it work.

If the driver did not install properly, try updating it first. If this does not fix the problem, remove the driver entirely.
