Im online,yet-Im not

PC stops loading web sites at random times. Some times Im online for a few hours,sometimes an hour or so. Goole,Opera and AVG browsers do the same. All devices "show Okay".PC shows Im online,connected, yet-Im not! Dont know what to do next. I hate Win10, love Win 7. Do not want to upgrade..any help out there?

NOTE. On Google ,.the top right corner of Google Page, the icons, email, images,flask,etc. dissapear, thats when I lose connectivity.

Online but not online!What causes the Icons ( email- flask-images and pic.) on Google page, top right corner to load ?They load an instant after the full page is loaded. When they are loaded -all is Okay, but when they randomly disappear after being loaded then I can not use the internet even though everything says I’m online and connected. Online sites/pages simply will not load. Period. Must be something in Win 7 OS causing this but what? When this happens all browsers stop loading..

Yes,I may have to wait hours or more to see if that helped.Like I stated the event happens randomly

Problem solved. Turned out to be a faulty ISP,,took awhile to figure it out but....

Thank everone for your assistance.

Jim..end of help
