It seems that my computer is choosing when to present this problem at random times. If surfing the internet, it sometimes chooses not to render any of the page content, see first image. Sometimes, it chooses to only display images after I roll my mouse across the screen. Sometimes, it chooses only to display the previous tab's content, other times it renders the font from the previous tab. What part of my computer is going bad? It's hard to pinpoint, but this time I got some screenshots. Guess it is time to upgrade or go Ubuntu. Would appreciate any help. Thanks!
