This happened once before and it went away by itself, I think...or, I accidentally pushed some key that corrected it. Also, if it helps I have Sticky Keys on but I always have them on so I don't know why pages would flicker now.

What operating system are you running? –  CodeBlend Sep 20 '11 at 21:22
    
Win 7 64-bit... –  verve Sep 20 '11 at 21:43
    
Google around I say it seems a few people have a similar problem but the solution can be very specific so one specific forum may prove more useful. Is this a new PC? –  CodeBlend Sep 20 '11 at 21:48
    
Yes, an HP desktop but the problem has only risen one other time for a few minutes. –  verve Sep 20 '11 at 22:05
    
If it's a local shop then if it is now persistent you can to them to show them the problem reproduced and make it their problem –  CodeBlend Sep 21 '11 at 13:32

I have seen this problem and it is either a poorly spec'd PC causing problems, settings such as virtual memory allocation, hardware issue or something as simple as below;

Why does my screen flicker when viewing web?

I think my problem was that I did not restart my computer after downloading the Adobe update. I restarted it and it seems to have gotten rid of all of the flickering.

Haven't had any Adobe updates. –  verve Sep 20 '11 at 21:44

What kind of flickering is it and what kind of pages does it happen with?

I find that the pages that exhibit this behavior the most are ones with plugins like Java or Flash. This is because they are not drawn by the browser, but by the plugin, so there is a bit of a disconnect between the plugin updating its part of the page and browser drawing the rest of the page during a scroll. It is not as bad with a faster system since it can handle the updating much quicker than a slower system, but even so, with the advanced and dynamic web-pages of today, pages put a much heavier load on the CPU (they "scale" with hardware advances), thus causing lag on anything but bleeding edge systems for some sites.

Just a slight flicker on even simple webpages with just text. It's more obvious on this blog page I was just reading: thoughtcatalog.com/2011/how-to-open-a-door when I scroll down using the arrow keys. –  verve Sep 20 '11 at 21:46
    
@verve All pages? Google search results? Does it only happen in the browser? What about scrolling a document in a text editor? –  Bobson Sep 20 '11 at 21:46
    
Well, in Word I don't see any flicker; just scrolled through a short document. And on this site it's barely noticeable. –  verve Sep 20 '11 at 21:52
    
On this site it looks like it's more of a wave than the blog. On the blog it looks like the text is "blinky" when I scroll through. –  verve Sep 20 '11 at 21:58
    
Do you have another browser available to test? What about other things like games? Do they display slowly? What happens if you drag a large window around the screen quickly? –  Bobson Sep 20 '11 at 21:59
