I could not boot the other day so I spent a few hour pulling everything out and checking memory components,etc.m taking the battery out finally fixed the boot issue but now there is no Internet or network detected or network adapter. It is not the router because pc in the other room is working fine on same connection. Mseems like a CMOS or bios issue. There was a message before boot about reverting to default bios settings. I can't update or remove driver because it is not detected and no Internet. Any ideas much appreciated. Thanks!!!
You have probably fixed this by now, but I'm guessing that the message about reverting to default bios settings is your problem - I had a similar problem when I moved my pc near to my router and wanted to use the wired connection - it was disabled in the bios.
Just enable it and problem solved :-)
