Well, it took months of figuring this out, but basically what caused the issue for me was my computer keyboard!
I have the Corsair K65RGB keyboard, which actually has firmware. Apparently, because Corsair’s Utility Engine is kind of a piece of garbage, I never got notified that I needed to update the firmware.
On a whim about a month ago, I did more digging into the PC freezing error, and decided to check every peripheral for my PC, and re-install all drivers for basically everything.
When I re-installed CUE, it finally notified me about a firmware update - I did it, which allowed me to update to the new version of CUE itself, and I have been without freezing ever since.
Now… how many here have any keyboards from Corsair, and if you did, did you have this freezing issue?
