They both are freezing up. I haven't had any problems in the past. What could have changed? What can I do to correct the problems????? I have to shut down/restart my computer to be able to do any thing else. I have an HP Pavilion 4453 that aprox 18 mos old. I would appreciate some help on this. <BR />Thanks, J.
