Howard,
things are still much better than before - but within the last two days I still got 1 random restart, just when shutting down Windows.
Remember - the last dump I sent was a memory error. Please find enclosed the dump of the recent restart. After the restart I did NOT get the message that my system reboots after a severe error. As far as I remember, you have the opinion that this mostly occurs on a hardware defect.
After this restart I replaced the memory - just in case it was faulty. I will keep an eye on this problem, but could you please clarify what was the reason for this restart.
Thanks a lot.
Daniel
