My desktop machine started having random crashes last summer when

anything between 3 minutes and a month, now it's a few hours
at most.
I never found anything interesting in the logs.
Most likely, this is some kind of hardware failure. I have fixed many
machines which passed memtest over a period of more than 3 days by
changing the memory modules. A BIOS bug, an overheated chipset and/or
CPU, faulty memory or simply a chip on your mainboard which got
damaged, it can be anything..
