The power supply is a Corsair AX850, purchased around 2014, and has been rock solid, trouble free with the prior motherboard/CPU/RAM. The issue is that twice now my new system has shut down suddenly, (Windows 10 Pro, no BSOD), and I'm wondering if the power supply is at fault here, or there is some other hardware issue. I have no understanding of AIDA64, so I need step by step instructions here to record power supply voltages and power output, (or other aspects of the hardware) so I can spot any issues that might lead to a system shutdown. In between shutdowns, it has worked perfectly normally.

I am hoping that AIDA64 can help pinpoint the source of instability that has caused my new system to shut down twice now, weeks apart, without any warning. I recently bought AIDA64 Extreme, version 6.25.400, dated, latest available.
