I'm using Internet Explorer 11 on my Windows 8.1 laptop. When on the web (usually news sites with video, photos, etc., the surfing is slow and choppy (hesitant when scrolling up/down). After a few minutes, the website page goes blank (bright white) and I will either get a message that "the internet has stopped working" or sometimes the page will recover and start flashing.
I have gone as far as "Refreshing" my laptop (gone back to factory default, leaving personal files), but the problem started again right away.
I have also run Malwarebytes, but no threats were found.

Thanks for any help you can provide!
