In the event viewer these are the error codes I can find. I have not written teh full Microsoft codes down but will re-post if necessary.
Centrino notebook 1.7 Gig Pentium M based on Mitac 8050. http://www.mitac-mtc.com.tw/Products.htm
I have upgraded the processor from 1.4 to 1.7 several months ago but I do not think the problem is processor related as it has worked fine until very recently.
The problem is that on heavy usage, eg., large file transfers or virus scanning the blue screen apears and the machine goes into memory dump mode and re-boots.
During normal use the machine apears stable.
I am sure that you will need to ask some questions to enable an answer so please ask with reasonable directions where to find the answer.
