There are no memory dumps in the attached zip.
To generate memory dumps, enable Driver Verifier. This will generate BSOD when a faulty driver causes crashes. Once you get 1 or 2 BSOD, re-run the SF diagnostics tool and grab the zip and upload here.
But before enabling Driver Verifier, click on:
Start
Run
Type MSCONFIG and click OK.
Under Services tab, check "Hide All Microsoft Services" and then press Disable All.
Then under Startup tab, click on Disable All.
Press Apply and then press OK.
Reboot your computer. See if that helps you to keep the system stable.
