[SOLVED] PC random crash with dual monitors

[Midnight5amurai]

PC build was running fine with one monitor, my second finally came in and it was working like normal for a bit, but now it randomly crashes and restarts. All usage numbers are low so I'm not sure whats going on (I'm also new to pc building, so I'm probably not aware of something I did/didn't do). I did notice this time, that the qled on the mobo went solid orange then red before it finished shutting down. If anyone has any ideas, I'm open. Pretty sure this happens a good amount I keep finding different solutions for other people, but they've had different symptoms.

Here's what I have in the build

MOBO: Asus Rog Strix X570-F
CPU: AMD Ryzen 9 3950X
GPU: Sapphire Pulse Radeon Vega 56
PSU: Corsair RM 850X
RAM: 2x Corsair Vengeance Pro 16GB
Storage: 2x Corsair MP600 1TB
Main Monitor: LG Ultragear 27GL850
Secondary Monitor: LG Ultragear 27GL63T

Look in Reliability History and Event Viewer for error codes, warnings, and even informational events that correspond to the crashes.

What are you referencing as "usage numbers"?

What happens if you swap "main monitor" and "secondary monitor"?

Oh sorry, my CPU and RAM numbers are low. Processor hasn't gone past 20% I think, it usually stays below 5% until I game; RAM rarely hits 30%.

Event errors show a "cache hierarchy error."

I googled the error and included "3950".

Found a number of links. For example - AMD:

https://community.amd.com/t5/processors/whea-cache-hierarchy-error-processor-core/td-p/392750

https://www.techpowerup.com/forums/...booting-during-gaming-cache-hierarchy.274053/

However (full disclosure) I am not able to pinpoint any particular cause or solution.

Read the links and do some additional searching by revising the search criteria as necessary.

You may discover some other indications of what may be going astray.

Take a closer look at BIOS/UEFI, drivers etc. Determine what is currently installed and if your build is up to date.

I am also going to move your post to CPU category in order to solicit more specific suggestions.

Thanks for moving it.
I'm going to try running Prime95 for a bit to see if anything pops up. I'll also look at my bios. Maybe swapping my monitors may do something, but its odd if adding a second monitor messed with my pc, even though it didn't start until the day I added it.
