Just to reiterate, I've got the wireless router connected to the computer with an ethernet cable. (maybe that's why it says "media disconnected" above under [03] WiFi?) Everything else in the house is running from the wireless.
Also, on the blue screen I get code 00x00000124. I got various interpretations of what that meant when I searched on-line. One was inadequate rear ventilation which doesn't seem to be a problem with mine. Thanks
