Setting up the new computer

March 14, 2009 JimK Leave a Comment

This is the part I like: Unpacking the new machine. Hooking it up to the cheap mouse and keyboard that it comes with. Plugging in the power cord, hitting the switch, and breathing a sigh of relief as it boots into the setup screen. Configuring a few basic options. Right-clicking on the Computer icon, selecting… [Read More]

It turned out that the two events occurred simultaneously, suggesting a common cause. I used Windows Explorer to transfer a much… [Read More]
