Try the steps listed below to troubleshoot the issue:

  2. If clean installation was done, refer the installation guidelines for Windows 7:

In case, if the issue still persists, perform a system recovery to factory settings. Performing system recovery will reinstall the pre-installed operating system, applications and the drivers.


Have you created the recovery discs?
