Crash

Bexear  What exactly did you do: move the same memory modules to different slots, or swap them between their slots, or remove a module or two?  It's possible the RAM is bad or one of the slots is, and if you want to investigate further, you'll need to do some testing.

The gold standard is MemTest86, testing each module separately and in at least two different slots on the motherboard.

Since this is time-consuming, you can use Microsoft's built-in memory diagnostics first:

I wouldn't consider a pass from this tool to be even close to definitive, but if it does flag an error, that's probably accurate.

Finally, I'd like to know what RAM you're using, by product number.  If you don't have that handy, you can find it on the modules themselves.
