Yes, yet another bit of advice from a user, but this one is at least
*** What I do**
rather than what I say !!
#1 thing to do 1st is to check your memory, what a stress test program.
Yes MSFS is a great Stress test program, but it does not tell you if your issue is a memory issue.
So use a FREE tool like memtest86
Easy to do, set it to run overnight while you sleep, and take a look at the results the next morning.
This is a reasonable definitive test – PASS or FAIL.
If it fails, there is really no point in perusing any other more complex diagnosis, till you get the Memory stress test running 100% reliably.
And just because it passed last month, does not mean it will pass today… that the nature of Memory FAILURES – they happen .
Also note, memtest86 does NOT run under Windows, so it is purely a memory test, not affected by any Windows OS issues – so if Memtest86 fails, it does not imply that you need to re-install windows … something that nobody want to do unless 100% necessary !
Of course, non of the above helps X-Box users
