Test your Java
http://java.com/en/download/testjava.jspFreeze with white screen sounds like java got stuck somehow...hence no error message in CMD window
Did you (or Windows Update) change your graphiccard drivers?
Could it be thermal problems with your PC or faulty Ram that makes it freeze?
Did you (or someone else) changed Router /Firewall settings?
What Antivirus/ firewall are you using?
If you use default client and an error message pops up - go to details at message window bottom then middle Tab to get details about the error
