webmail

I recently purchased a new computer.  I had so much trouble with my email screen freezing up and going nowhere with my old one along with other problems that I thought a new one would fix the problem.  However with this new HP I am having the same problem with cox.  Its takes forever to load to even open the emails.  If I delete or try to reply again it freezes up.  I am not a wizard at computers but there must be something I can do.  I have tried using Google Chrome to open and the internet if that makes sense and still have same problem.  Is there anyway you can help me with this?
