1. Upgrading graphics cards is a straightforward process. Simply right-click on the Windows Start menu and select "Device Manager." Then, locate "Display adapters," right-click on your graphics card, and choose "Update driver" from the drop-down menu.

An unstable network is the cause of error code 1608. Kindly verify whether your network connection is functioning normally or switch to a more reliable network.
