Beware? It seems from the thread that the OP simply messed up their Windows registry by watching videos when updating their drivers, when they should not have. Am I missing something?
It screwed my pc up, since i reinstalled old driver version no problems. I was getting messed up sound when streaming videos from youtube as well. Just be aware of it, install old driver version instead of latest. Try a newer version in a few months. This is nothing new, Nvidia have a terrible track record even destroying $500+ cards by making the gpu run 100% when idle. Some of those threads have gone past 100 pages with so much outrage.
Edit - Glad you got your fist component, and with a nice reduction from the price on your parts list above, works out to around £180 which is cheaper than I got my RX480 for almost 2 years ago at £212, just before the mining craze bumped the prices up.
