I asked you this in posts 4 and 5:

Did you install some software like a program or something right before this started?

You replied with this:

i dont think so, my brother probably did but he wont tell what. o my goodness sorry for the lack of info

Now lets check to see if any software was added.

What I would suggest is Uninstalling All Programs you don't need or don't want anymore through Add/Remove Programs

Do this by going to

Start and then to Control Panel
Click Add/Remove Programs
Carefully choose the program(s) you don't need. In your case it would be anything installed right before this all started.
Click on each Program then click Change/Remove and Follow the Uninstall Instructions

You may be prompted to Restart your computer.
Restart once you have all the programs you don't need uninstalled.
Be careful not to remove anything needed by your computer, some of which you may be unfamiliar with the name,
