OK, I usually am the master of these things, but here is a new one to me. So I have a 3900x, a X370 Taichi motherboard 4 x 8 gig ram, an AIO, and a 2060 video card, with an 850 watt PSU. For a year, all was fine, then the last few weeks, after about 2 days, it just shuts down. I unplug the PSU for a few hours, plug it back in, and then power up. All is fine for a few more days. I changed out the PSU to a brand new gold EVGA 850, no change, so thats not it. The temps are fine after boot, even@100% load.. But about 2-3 days later it will shut down again.

Motherboard getting overloaded with a 3900x ? Old VRM's that are a little weak ?
 
Looking thru the event viewer I couldn't make heads or tails of it. Did a search and saw some people with the same problem. They were saying theirs was a memory problem. I did update the bios. I changed the xmp(whatever Amd call theirs) memory to the standard default 2133 instead if the 3200 and so far no reboots.
 
My old X58 Asrock Extreme SATA ports eventually failed. Well I assume it's the ports. I'm finding this program called 'Mirror Folder' is giving the drives issues on my replacement EVGA E770 so maybe the Asrock is fine. Another similar case: one of the USB 3.0 ports on the replacement EVGA burned out. I was doing large file replacements on an SSD attached to a USB 3.0 to SATA adapter and so far it seems it wrecked one USB 3.0 port for sure and the other seems to be going.
 
I just updated to the latest windows build and so far no reboots. Will see how it goes

BTW, since this thread started as my problem with my 3900x, did everybody catch the problem solution ? The motherboard has 2 CPU connectors, and the PSU only had one. When I changed to a PSU with 2 CPU power connectors all the problems went away ! And now for weeks with no problems at 100% load 24/7.

Would a bios update cause me to require needing to use both cpu power connectors? I had the 3900x since it first came out. only problems I had was memory would cause problems when running XMP profile. After a bios update or 2 it was fine until recently.

Are you using the GPU too? Because for a while the problems seemed to go away when you didn't load the GPU.

Its possible tat the bios was pushing it harder, so yes maybe.
