Recently ebayed New CPU, (no probs) new RAM; also no probs. And new MB. And also no probs. Well done everyone! (I hate to mention that MSWIN 10 also had no probs.) Just fit it, fire it up and let it do it’s thang… Of course I am no longer “licensed” to use MSWin 10, but it did not choke, just refreshed itself. And carried on regardless. I am very surprised. I was going to do a 100% re-install of everything, and I probably still will, but SO IMPRESSED
