--=-yzl6hXUJcAbRwXX3j53y Content-Type: text/plain; charset=us-ascii; format=flowed Hi, This laptop is new (I bought it just earlier this year), and I have also dual booted it with Fedora Linux which works completely okay, so I don't think this is a case of a CPU hardware issue ... Thanks for your help, though.
