If Something Goes Wrong

The Windows® operating system is not working

The operating system responds differently from the normal routine.

The screen does not look right.

Unless a hardware device has failed, problems usually occur when you change the system in some way such as installing a new program or adding a device.

If you experience any of these problems, use the options in the Startup menu to fix the problem.
