Ok, this sounds stupid....But dig this.
When my 2 of the last 3 computers crashed, it was during some of my trips out of state. (The one last October wasn't, but it had a design problem in it that was fixed, as it was only 4 months old).....But those other 2, the problems started after I had been on wireless WiFi at the places where I had stayed. Somebody pointed this out to me tonight....So, I went in a eradicated them as connections out of the 'communications manager'. And, on the first attempt to load the BullyBoard Index page, there is was. This was after all evening of trying to get the page to come up without succuess.
So, hoping that is the solution. If it is, I'll never use Wifi ever again !
