Websites not loading... Sometimes

[Georgeskal]

Hello, i have a problem with my pc,i have an old desktop still running windows 7 and i plugged in my Ethernet cabe, it says there's internet and everything but whenever i want to open a website nothing loads, it hits me with the "site can't be reached" but it doesn't happen all the times sometimes it just doesn't load stuff, like if i go to YouTube it shows the thumbnails and loads fine but when i click on a video it says site can't be reached again, and my internet works fine on all other devices. I already tried restart pc/ router changing to google dns, tried it on Microsoft explorer clearing cache and updating chrome. Could it be compatibility issue with windows 7 or something? Answers would be appreciated

Which browser are you using?

Is it still safe to use Windows 7? I think that has not been updated for some time.
