Windows 10: My monitor won't connect to my laptop, the audio is crackling, and the loading is choppy,...

My computer screen suddenly turned black, but everything was still playing, and my second monitor was still open, but shortly after, it disconnected. I shut off my computer and restarted multiple times, but it won't connect to the computer anymore. Plus, my audio is crackly, and my loading is choppy, almost like half the framerate.

Audio from laptop speaker crackles

I have a Dell Inspiron 15 laptop that starting making crackling noises in it's built in speakers last week. It makes the noise when playing any kind of sound. I ran the audio troubleshooter and nothing was found. I rolled back a display
driver update I got a few days before hand but it was still making the noise. I then uninstalled the audio driver and restarted my laptop. When it came back on, the driver came back by itself and it stopped making the crackling noises. But tonight it started
doing it again. I ran the troubleshooter again and it suggested turning off audio enhancements but nothing is checkmarked except "immediate mode". I removed the checkmark but the sound is still crackling.

 

Crackling audio. Skyrim + other games

USB headphones have never been kind to me. They always hiss, pop and crackle. The fact that you can hear it when no audio is being played suggests it's a power /connection issue.

Do you have any 3.5mm or RCA based headphones you can try?
