I am having problems with my computer freezing up so many times that sometimes there is no way out without restarting which means losing work done during this session! If anyone has had similar issues try updating everything possible including windows updates since they are usually behind what's available in other countries/markets like Europe etc..
Sometimes when we have new devices installed (such as printers) our computers become unresponsive until rebooted after about an hour but not always!! Very frustrating especially if working via remote desktop connection where i cannot access any files stored locally unless logged off then back onto local machine again before reconnection.
