Presuming "frozen PC" means "unresponsive and must be forcibly rebooted, there would be no retrying with the program without restarting.

What with Windows Update and the variety of other similar OS- and application-level auto-updaters, is getting the computer into a very similar state likely? I'm not sure but my gut says no.

That said, at first I was imagining a desktop computer with 4 or 8 memory modules, but given a machine with just 2 modules, maybe it follows that one module usually gets filled with "core stuff" and the second, defective module somewhat infrequently sees "big user stuff" after the first module is filled, and I guess that isn't too much of a head-scratcher when it comes to identifying the source of the problem.
