Solved Another BSOD Issue

Trying to convince my girlfriend to take the PC back to hers today, and over Xmas. She's less than keen to have my large PC hanging around her place, but we'll see.

Been testing each of the 6 RAM boards in turn today. For a moment I thought I'd found one that wouldn't test, so I went on to the next board. Finally I had tried all so plugged in the suspect board to retry, and it started testing instead of just showing a blank screen ! Unsure why. Maybe I'd put it in the wrong slot, or something. It will be offputting if it passes along with the other 5.

edit
Yes, it did exactly what would cause most confusion. The 6th board ran 2 passes without error so out that came and the suspect 5th board put back. As one might guess, this time it showed no errors. So, I installed all 6 boards back into the slots that they came from, the test was running all night, no errors. Still running in fact.

Unsure whether this is good or bad. On the one hand it seems to be working, but all that's occurred is the boards have been removed, then put back again. No idea why they'd need that after years of being ok. On the other hand, if there's still an issue it's gone into hiding and so I can't see how we can chase it further. (Knowing my luck the memory will prove to be a "red herring" and it'll crash out on something else when going back to Windows.)

OK, I'm loathe to claim it's fixed only to find later that it isn't but: it's been on a few days now, admittedly mainly behind the screen saver but, no BSOD during that time. It may be that simply pulling out the boards and putting them back, achieved something; but for the life of me I can't imagine why, after years of working ok undisturbed, it was suddenly in need of some movement. Maybe the contacts oxidised or something. In any case, as long as I can reopen the thread if it starts failing again, I guess this could be considered solved ?

Can only say that, although I've not had the need to use my PC at my girlfriend's place, it has been left on continually and is still going behind the screensaver; no crashes.
