Not sure if its any help,they won't fix themselves.
desktop windows manager crashed on 29th, it is the part of windows that talks to GPU. it didn't cause a bsod but its another thing pointing at drivers.
it doesn't really tell me what caused the USB error.
Ive noticed that the restarts with no errors moslty seem happen when I have a browser open, both monitors go black and then I see the bios boot screen
the blue screens can happen at any time really, and theres been other times where the PC completely freezes, the displays stay on, but no matter how long I wait it doesnt go to a blue screen, its really odd
Im going to follow the tutorial you have provided now.
