I'm feeling insecure about stability of the computer after numerous instances where I had to restart the computer while doing sth with it.
Civilization VI was crashing and giving a BSOD or a black screen with nothing to do but restart and if I remember correctly sometime ago I ran both Windows Memory Diagnostic and MemTest86 and neither gave an error.
Later, Everspace was crashing so I ran Prime95. Blend tests failed after some hours though Small FFTs test did not fail for like 16 hours.
Yesterday after the latest Windows update hidden icons were not displayed and date and time was wrong. I couldn't system restore to the latest restore point wihch was after the latest update, but I restored to the previous update and it updated again this morning, no problems about hidden icons or time now.
Previous to all of this, CPU had been overclocked and at some time it became seriously unstable so I returned it to stock settings. I saw the date and time set wrong at startup maybe 3 times since then but generally it is correct.
Can you help me overcome this instability ?
