Given the story at https://www.cnet.com/forums/discussions/i-start-a-download-pc-freezes-and-net-cuts-off/ it does sound like a driver problem. The old PC has the right drivers to pull this off. Your new one? Not so much.
126.96.36.19924 (from the Speccy) looks to be from last year.
A lot of folk are trying to go with what Windows 10 picks for drivers. Sorry folk, Microsoft has yet to nail drivers yet.
(Just a heads up, I'm probably seen a lot in this section asking all kinds of things. I will be here for a while as every computer I build/buy is a disaster.)
So, I built my new pc and started to see a weird problem, every time I boot my pc the second monitor works in bios/boot but then it switches to my first one and the 2nd one isn't even detected. It used to fix itself by putting the pc to sleep and waking it up, but that doesn't work anymore.
I don't think it's a driver issue as when I put this gpu into my old pc all works fine.
GTX 750 Ti
Ryzen 3 2200G 3.50GHz
8GB Corsair Vengeance RAM clocked at 2400MhZ
Gigabyte AB350 Gaming 3 MOBO
CXM 550 80+ PSU
