It's not that it freezes its just that it takes a very very very long time to load... it helps if you disabe some system process if your running the game but I wouldn't advise it unless your comfortable doing so. ( it speed up the computer a lot by disabling useless system programs. )
what processor and ram do u have for ur pc?,try disabling use load ups there start when pc does,examples bein real player,adobe,skype and bunch of others just run essential programs and antivirus guards,should notice a increase in system speed,to adjust that stuff permanently put in run option on start menu 'msconfig',just dont mess with microsoft windows settings,dont want to damage anythin
