Hah, I had just followed the advice in that article :-) it didn't result in any problems. The annoying thing is, as long as I don't play Ark, things seem okay. As long as I don't install Photoshop/Lightroom, things seem okay. I'm not sure if it's either of those applications causing trouble, because I'm afraid to try again. I don't feel like re-installing Windows yet again... I hate when problems are this vague!

I'll check out the Ryzen 5 news! Replacing a pc after 6-7 years that's in use basically every day seems warranted anyways...
