I started having trouble with my CPU about two weeks ago. My browser is getting redirected to random, sometimes semi-related, websites after I search on Google. Also, I tried doing a system restore and found I couldn't, it wouldn't let me and it gave no error message, nothing happened when I would click next to start the restore process. In addition, disk defrag will not work either. Any help on how to stop these problems and get everything back to normal would be greatly appreciated!
