So, finally I got old enough to qualify for a Blue Screen Of Death.
No problem, still under warranty, I thought.
The well-known PC builder's technicians, however, blamed Windows for the fault and not their hardware. Elegant exit for them.
Good to have Colin in town.
He not only found the culprit (a faulty SSD) but helped to write a report that could help to get my expenses back.
Well Done, Colin! You have been promoted to the family's preferred computer healer.
