I have tried running my security scans--I have some office depot support thing, as well as McAfee Total Protection. I've restarted my computer, disconnected then reconnected to the wireless server I'm using (home). No difference. I've also tried testing my internet connection (a right-click option on the connection bar symbol)and was able to indicate a specific site I was having trouble with (www.google.com), and my computer detected no problems.
I also had a friend tell me to look at my task manager, but I do not know enough about computers to identify anything "weird." I believe my computer uses Windows 7 (as that's what's on this sticker here

I'd also guess that the problem is my computer and not my internet server because two other laptops and my smart phone--all using the same server--have no trouble
So, what should I do? Is this a little problems that I can easily fix? Do I need to take my computer in to someone?
Thanks!

(Also, I apologize if this is not posted in an appropriate area. And also for my lack of correct computer speak

EDIT: This began today.
