I find the problem occurs on an irregular basis, usually on websites where there is a vast amount of scripting for ads, or video links, such as news sites.
It can happen when you have a slowdown in network speed due to a large number of users on your ISP or router - it can happen when someone working on the website is doing an upgrade or modification to the webpage (this happens hundreds of times a day on news sites) - or it can happen when a large number of users log onto the site within a short period (for an interesting or developing news article of great general interest).
I find if I just kill the page and reload it, via the Chrome browse history button, it will generally reload without problems.
We have no problem with you asking a "dumb" question - but we do have a problem with you admitting your transgression about reading the DM. There's nothing we can offer for penance for that.
