Hi there,
I have many Customers who are your age and older and we still manage to help them--most of the time! LOL. Neemo's little script is really quite easy to use, but if you are not comfortable with running it, get a hold of a tech savvy friend, neighbor, or family member, probably younger than you to assist.
In the meantime, you should be aware that a few of our longtime members here have identified problems with Chrome going back 2 years or more before W10 was released. The one fellow I'm referring to built his own machine and is quite advanced a user. His machine is newer than all but 1 of my computers, and the other people who also reported this problem on computers built in 2012 or after (5 years old). Most of my test computers are 8-10 years old, and for some strange reason don't suffer the weird Chrome problem.
A couple of other questions for you to help us; do any of the other browsers on this computer have problems loading pages from your bookmarks or saved addresses such as Edge, IE11 (Internet Explorer v11), or Firefox?? Or does it just happen with Chrome. Uninstallation of Chrome sometimes has fixed this problem, but make certain that you disable your AV (Antivirus) program first, otherwise your Windows can become corrupted, and you won't be able to reinstall Chrome to make it work again without completely reformatting your drive and reinstalling W10 from scratch--and you probably don't want to do that yourself if you've never done it before.
Other things to try:
1.) Take your computer into the room in your home or apartment and plug into your router or cable/dsl modem with an Ethernet cable if you have one--they almost always come in the box with your Wi-Fi router or modem when you purchase it or your ISP sends to you. See if the problem is resolved. If it is, it's probably a failure of your Wi-Fi drivers to work with the new W10 CU (v1703). Neemo's script could help us to identify the actual problem there.
2.) Try changing your Network settings to make both your DNS servers the following 2 IP addresses:
DNS1: 8.8.8.8 and
DNS2: 8.8.4.4 save and reboot your machine. Test your Chrome bookmarks again. If it works-something in your network settings, such as the Wi-Fi driver above in #1 got messed up in the update; this fix often works!
3.) Try disabling and then re-enabling the Wi-Fi using a keyboard combo if on a laptop such as
<Fn-key+F7> or similar. You can download that info from your computer or laptop manufacturer's website for free usually in PDF format. This often works, as if your computer is using DHCP or auto-IP address assignment, the act of disabling and re-enabling your wireless radio in your computer or laptop will force it to reset all the wireless settings in windows, grab a new address and reconnect your computer to the Internet.
Let us know how you get on.
Oh, and I almost forgot if you haven't scanned for viruses/malware you should use your built in AV program to scan/remove all found viruses. If Chrome bookmarks start working again, you simply had a virus that attacked your Wi-Fi settings. Problem solved!
Best of luck,
