I would be interested to know whether any one else using windows xp pro has a problem with the system totally freezing for no real reason. As a help, when it goes, the hard drive light just kicks out and everything just freezes, you cant even use alt_ctrl_del to bring up the task manager. Usually this happens after software has been added or removed. It usually happens anytime, on just boot, or particularly doing defrag. If I do a selective reboot using msconfig to disable startup and services, then its ok if i carry out a defrag operation like that. So it could be a change in the settings. Once I get it right its ok. WHy is XP so sensitive, if MS keep preaching that its the best thing since sliced bread, then why to a lot of guys prefer to stick to their 2000 or 98SE!!
