Glad it wasn't memory. Side story example, on software updates that sometimes cause problems, my Google Chrome browser had stopped working for a week. Error reports weren't helpful at all. Turns out my firewall manufacturer had introduced a bug accidentally which they just patched (took them a week and a half). Even though connectivity had the browser going through the firewall, and exemptions were made to the rule set, the actual update introduced interfering issues which got patched out.

So sometimes patches can cause issues. Even specific Windows patches, and it's always good to know how to roll back a driver (graphic card) if needed or how to uninstall a windows patch (if it causes errors)...

The dust settled, thinking "what a fine home, at least for now" not realizing that doom would soon be coming in the form of a vacuum cleaner.
