Hello,

Start out by uninstalling Daemon Tools. When done, remove SPTD itself with the tool found here: DuplexSecure - Downloads

Did you change the setting for your page file? It almost looks as if the page file has been manually set to approximately 8GB, the same as the installed RAM. If that's the case, change it back to "System Managed", and then reboot.

Also run hardware diagnostics. Start with the three Prime95 tests: https://www.sevenforums.com/tutorials...t-prime95.html

Finish up with Memtest86: RAM - Test with Memtest86+
