Often, when Windows asks you to upgrade your system, you don’t have time for it and you put it off for later. This is bad news for your operating system and can cause big damage to your PC and the data on it. Therefore, make sure that your computer is equipped with the latest updates: Click Start, then select Settings -> Update and Security -> Windows Update -> Check for updates.

After that, restart the computer. If the problem persists, proceed to the next solution.

2. Update main “trouble” drivers: Internet, Wi-Fi, graphics.

The best action to take, of course, is to update them by going to the manufacturer's website and downloading the latest update for the corresponding driver.

So, to update the graphics, Internet, and Wi-Fi drivers, do the following:

Simultaneously press the Windows key + R. This action will open the Run program. Type “devmgmt.msc” and press Enter. The Device Manager will open. Select "Display Adapters" (for the graphics driver) or "Network Adapters" (for the Internet and Wi-Fi drivers). Right-click on the appropriate driver. Next, click on "Update driver software."
