In some cases, the Technical Support staff will request you to generate an MSINFO32 .NFO file. This file contains detailed information on your PC's hardware and software specifications which the staff can use to diagnose and troubleshoot the issue you are currently having.
Generating the MSINFO32 .NFO file:
Go to Start > Run or ⊞ Windows Key + R.
On the Run prompt, type "msinfo32" then click OK.
On the System Information window, select File > Save.
Browse to a folder, type in a filename then click Save.
It's recommended that the folder and filename you choose can easily be remembered and accessible.
Make sure that the Save as type is set to System Information File (*.NFO) as well
