Page Cannot be displayed.

Some pages refuses even try to go look for page online: "what? your homepage in somewhere online? nah dude, forget it, im not going there. here, why don't i pull up a local page i defiinately exisit - ta da! Page Cannot Be Found! ain't that a beauty?"
When I try to access
www.rr.com
www.roadrunner.com
www.twcnyc.com
tv.yahoo.com (http://64.58.76.252/ number works though)
within 1 second I get a DNS error. Now I know that certain people will be able to access these sites. By the way how many people use mozilla netscape and are you able to access the sites there. I read and other people that rr sites you can't access if you are on Earthlink cable.
Also every day explorer keeps crashing. It's fine until I try to close a open window or try to close Windows Explorer only if I leave it open for a while then try to close it.
Plus to make matters worse when I try to run disk cleanup it just sits there, stalls and does not respond. I left it running for a half hour and it just sits there doing nothing and then I have to use task manager to close it.
