Laptop Freezes

[kloofnek]

.My laptop has starting play up...it takes me three or four goes to get it working properly ..

I boot up,get to home page and maybe onto the site I want..then it freezes(the curser still moves about ) cannot restart the usual way and have just turn it off by the on/off button...hate to do that...this happens as I have said,3 or 4 times ..then it works fine for the three hours or so I am on it...so?????????? I once saw a pop up saying something about"dumping ground" ????
Friend of mine has a disc which wipes the hard drive clean...would that help.?

Download, install, update and run in safe mode a free application called malwarebytes,

Can I use it even though I have Norton installed?
