Hnnnggggghhh..
I can't figure out why it's doing this. Basically, I've been playing Bf3 up to now with no problems. I discovered I should be running it at higher settings, so naturally, I cranked the settings up to see what I could get. The campaign played just fine, but when I got into the multiplayer, I got a DX11 render error, something about a lack of memory. Alright, I thought to myself, no big deal. I'll just turn the settings down. Even back on my previous settings, I was getting errors. So I did the NEXT logical step, uninstall. After uninstalling and reinstalling, I was able to play a full game. I turned the audio settings to "War Tapes" (Mind you, this has worked for me in the past consistently, even with my new sound card and audio setup) and a few moments later, I got a Dx11 error. Not only did I get the error, but it took out my sound as well, forcing me to restart my computer. I have no idea what could be causing this...

Obligatory DxDiag for people that know how to interpret it.

I'm at a total loss of what it could be.
