Ok so some interesting developments. kemical, i followed your procedure and did a safe mode hard uninstall of the GPU driver(s). What was and is interesting, is that i managed to install one of the older versions of the driver still sitting in my downloads folder. Before hand theses driver install files where saying incompatible / use the geforce experience. Well now that this older version driver is installed i ran a couple of tests with the problem software, and it seems to be stable. So a tentative solution until further testing but that install being permitted to me is a big indicator that something was wrong, and has now been solved. Any way i will post an update in a couple of weeks if i have had no similar issues regarding BSOD and this operation.
One last technical question kemical, is it best that i post the whole folder from the crash extractor app, or would just the mini dump file suffice in the event of a future post on this thread.
And lastly. Big thanks to you both for taking the time to engage with this problem and all of your expertise. I really appreciate it. Thanks.
