Some websites don't seem to load right or at all

Personally...I think you have an malware issue.

Check out the post from this link having to do with malware fixing: http://www.computerhope.com/forum/index.php/topic,46313.0.html

Then ask evilfantasy or broni or some other malware specialist for some help fixing your pc. Like I said, complete formatting of pc and fresh windows installation would solve all the software problems like browser not working or whatnot, but I think you don't want to go that route yet.
