This actually happened to me not too long ago. Things would randomly just crash. Turns out it was because my RAM had bad sectors in it.
On linux I'd just restart whatever crashed and it usually went along fine for another 30 minutes. Worst that happened was btrfs would make my drive readonly until a reboot because it knew some shit was up.
On windows it bluescreened several times before corrupting the hard drive (was thankfully able to recover it lol)
