Diagnosing system crashes

[rubberduck]

Hi

Have been experiencing random system crashes, almost exclusively when the system is not under much load and when doing something non-demanding like watching a youtube video (however this could be pure coincidence as I hardly do anything stressful with my system these days).

In order to attempt to diagnose the component causing the problem, I have removed all overclocks on my system and reset Bios defaults to see if I still get crashes. Can anyone give me any further general advice or tips&tricks on how to diagnose system instability?

First I would check event viewer for codes?
If you removed over clocks etc temps should be fine but I would check it just in case
Also memtest86 could be useful to run for ram errors.

List your PC specs?

Usually crashes at idle could be down to too little CPU voltage at idle or not enough memory controller voltage

If your over clocked through offset setting a lower loadline calibration setting and more CPU offset will give you a slightly higher idle voltage while keeping the same CPU load voltage
