Code:
When I restarted the laptop with the new motherboard the fan worked for about three seconds, the DVD drive clicked, and then everything went dead. Tried this several times, several ways, but no difference.
Next I took out the new motherboard and re-installed the old one (I wanted to find out whether it was the new motherboard was at fault). But it wasn't the new motherboard. When I booted the fan ran for about 3 second, the DVD drive clicked and it went dead. Maybe the problem is being caused by the way in which I installed the motherboard (but I went very carefully and followed all instructions to the letter). However someone out there may have advice and suggestions.
