Ok...WiFi driver didn't work, in fact, I had to go back to the restore I did before downloading the driver. I am super impressed with your site and the experts that are helping me...I believe there is a solution to everything, and that is how I have tried to resolve problems on my own, being self-taught for the past 30+ years (Apple II+ was my first PC). What do you think can be the resolution of this problem? My company's IT man would say to just re-install everything, but I can't go that route because of the time it would take to re-install. I think we are close to a solution...we have never discarded hardware defects...I would like to think that my experiences with SONY Vaio systems will continue to be positive, but it is a possibility. Should I send you the MEMORY.DMP file I mentioned before?
