Crashes aren’t normal even in Windows. Rare crashes mean a hardware problem 99.7% of the time. Typically RAM as others have pointed out. The only way to figure that out is 4 passes of Memtest86+ without red. Yes 4 because the the first pass is a short one made to spot obviously bad RAM quickly. Less bad RAM might need more. I’ve had a case of 4 sticks that each pass on its own. Every two passed on their own. All 4 failed on the third or fourth pass. And if you think I tested for shits and giggles, I did not. I was see checksum errors on my ZFS pool every other day. No crashes. Nevertheless, if it wasn’t for ZFS I’d have corrupted files all over my archive.
