Tuesday 20th Sept computer (i5 2600, 16gig 1gig NVidea Graphics) running really well. FSX really smooth. Wednesday morning Win10 wanted to do an update no big worry I thought. After restarting the damned thing told me that Daemon tools was not compatible with this version of Windows, ah well didn't use it much anyway. Spent about an hour trying to get get rid of it, because the uninstaller was not compatible with this version of Windows. Revo deInstaller finally got rig the blighter. I then found that the update was the long awaited Anniversary Edition. Ah well let's have a cuppa, sat down and noticed that the screen-saver was working, that hadn't worked since Win10 was installed, (some issue with Saitek joystick) bonus I thought. Next up check Emails and have a wonder around the net, Waterfox would not let me onto the Google search site, Wikipedia and a whole lot of others, saying that the site not configured correctly that problem sometimes appears if the computer doesn't have the correct date, now that problem has appeared on another of my computers, the usual fix is to set the correct date. Well the date is correct so I tried Firefox and all was well again, once again no big deal. I then decided to have a play and fired up FSX with Ant's Tiggy at Bowerman, took off, about half way around the circuit FSX crashed, "Your computer has run out of available memory", never had that problem before even with the disc version of FSX. Tried to load different scenarios all with the same outcome. By this time I was starting to get a tad annoyed so cut my losses and do a complete install of Win10 and all software. After doing that and letting the Anniversary update do it's thing, I now have a working computer with FSX running really smooth again. What the problem was I still don't know, I see on the net that I was not alone in having problems.
Cheers
