That is a good power supply, so it is less likely that could've been feeding too much power to peripherals causing AIO to die. Motherboard settings could do it though.

Like I said, forget Intel's tests, they are too simplified, use OCCT. Its creator has YouTube video how to use it.

You should consult those that are experts in motherboard you are using on enthusiast forums.
In the meantime work with Dwaine and try to get clean bare install on separate boot disk (like I said, number of software you are using has bad reputation for introducing issues). Oh, yeah, and I would try uninstalling all 3rd party plugins for Resolve you might have, starting with Tintensity, at least for the duration of troubleshooting.
