I just updated my power suppy, graphics card, and ram. I started running fallout new vegas when the sound starts crackling and soon after I start playing the graphics randomly start skipping then going back to normal.
1030 power supply
8 gigs ddr2
I found the problem out. My headphones were shorting out and were cutting back in and out so fast that my computer was slowing down detecting them then losing them. I unplugged them and plugged a different pair in and it works fine now!
