OK, Betty:
This could well be a long journey. In the following, every now and then I'm going to ask some questions that may sound either patronizing or stupidly self-evident. Please bear with me because I can't see your computer and what's around it. And you don't have to go through this list in one go.
1. Is the machine plugged into the wall, or are you using the battery? If it's on battery power, the computer will work at reduced speed to save power. (You're most likely using the power cable, but I have to ask).
1.1 Remove any USB sticks or HDMI cables from the computer. This includes the keyboard and mouse, if relevant.
1.2 From your previous post I assume you are now using a completely 'new' computer with a 'new' Windows 10 version installed.
2. In Windows 10: Open the Start menu and click the Settings app (a small gear cog). In the Settings menu, click Update & Security. This will show you the Windows Update page. Windows is set to download and install updates automatically, in which case you will see some dots drifting from left to right. This means the update process is active.
If it isn't, click the button/rectangle that says 'Check for updates'. Your computer will start searching for updates and install them. If you get a message prompting you to restart the machine, do so. This could potentially take several hours because your computer is brand-new and needs to catch up with the latest Windows 10 version available. Let the computer download and install until it says 'Your device is up to date...' You will most likely be asked to restart several times. This takes top priority!
After that:
3. Click the small gear cog again (upper left corner) or 'Home'.
4. Click Network & Internet, and next select 'WiFi' in the left menu. Make sure it's On.
5. Select Ethernet in the left menu. It should say 'Connected' next to the icon.
6. Open the Start menu, and click on the tile that says 'Microsoft Edge'. This launches Microsoft's new browser called Edge. Spend some time browsing some web sites you know. Make a note of the speed at which it opens pages, or how many tabs you can open at the same time.
7. Open the Start menu, and bring up All apps by clicking the 3 horizontal lines in the upper left corner. Scroll down to Windows System. Right-click the app called Control Panel and select Pin to Start. This app is just as important as the Settings app. We'll be using the Control Panel later on.
7.1 This is a link to a user's manual for your Lenovo 310 that you can peruse in your own good time:

8. Go to Tom's Hardware and tell me how you're getting along.
Cheers,
