Now yesterday I noticed that sometimes if I open a video and do or open some other stuff at the same time it's running, or a few things in succession, it results in the video's audio emiting a popping/crackling sound. I used Device Manager and couldn't find anything that is causing the Latency. I didn't deactivate all the drivers, naturaly, but tried all the ones they advised to, as well as a majority of the non hidden ones.
The DPC stays below 4000 even while a video is running, and goes to a 200 at times as well.
