slow motion video and no audio, all browsers, multiple sites

Hello, banging my head against the brick wall of another conundrum. I've just started having an issue where all video (youtube, dailymotion, etc) is stuttering and playing like 5 or 10 frames a sec (just a guesstimate). Also doesn't play any sound except this weird distorted audio. I'm fairly sure the aliens aren't contacting me.

This has occurred in firefox, chrome, IE, and Edge. Private mode and normal, though few addons anyway.

Scoured the internet but about every thread I could find ended quickly and usually with instructions on updating drivers. This problem has even occurred before and at that time, updating my video card did the trick. I've confirmed that both audio and video drivers are updated, have restarted multiple times, I've checked and seen Hyper V is off, tried with and without hardware accel, run system troubleshoot (which only returns error of 'troubleshoot logs taking too much space on drive.' It then proceeds to tell me there is like 0.024 gb of space taken, so like 240ish meg?)

Not 100% certain what logs or dxdiag to include or anything, but I'm running a homebuilt:

Win10 pro x64
AMD FX quad core 3.6 ghz proc
16 gb ram
Nvidia GTX 1050


Please help! Now that I have kids I do less gaming and have to live vicariously through YT gaming.

HALP!

Update:

Just tried an online clip, same issue, downloaded it, got the issue on the win10 default media player, though in VLC video was fine, but no sound.
