Well, Pete, Celery and Technician,
Thanks for all the info and advice.
Regarding the Processor changeout.--I haven't done that, but both have the end Intel Number "05A",--which from what I've read on the 'net, means they should be interchangeable. I wonder if that means the pin pattern on the socket can accept the other processor pin pattern.
I've sourced a replacement MB---40 Euros. incl CPU and Heatsink. Ideal all things considered. Just swap it out. I#m putting an English Win 7 OS on plus MSE Security and Adobe Reader /Flash Player. MS Works. Aimed at English speaking immigrants, here in Germany. I've had it 4 years --cost me only 100 Euros with no OS. If I get 100 back I'm happy.
Thanks again guys. Have a great Christmas and success in the New Year!!
